The compounds of the present invention inhibit 2,3-oxidosqualene-lanosterol cyclase (EC 5.4. 99. ) which is required for the biosynthesis of cholesterol, ergosterol and other sterols. Causal risk factors that directly promote the development of coronary and peripheral atherosclerosis include elevated low-density lipoprotein cholesterol (LDL-C), low high-density lipoprotein cholesterol (HDL-C), hypertension, cigarette smoking and diabetes mellitus. Other synergistic risk factors include elevated concentrations of triglyceride (TG) -rich lipoproteins, small, dense low-density lipoprotein particles, lipoprotein (a) (Lp (a) ), and homocysteine. Predisposing risk factors modify the causal or conditional risk factors and thus affect atherogenesis indirectly. The predisposing risk factors are obesity, physical inactivity, family history of premature CVD, and male sex. The strong connection between coronary heart disease (CHD) and high LDL-C levels in plasma, and the therapeutic advantage of lowering elevated LDL-C levels are now well established (Gotto et al. , Circulation 81,1990, 1721-1733; Stein et al. , Nutr. Metab.

Cardiovasc. Dis. 2,1992, 113-156; Illingworth, Med. Clin. North. Am. 84,2000, 23-42).

Cholesterol-rich, sometimes unstable, atherosclerotic plaques lead to the occlusion of blood vessels resulting in an ischemia or an infarct. Studies with respect to primary prophylaxis have shown that a lowering of plasma LDL-C levels in plasma reduces the frequency of non-fatal incidences of CHD, while the overall morbidity remains unchanged. The lowering of plasma LDL-C levels in patients with pre-established CHD (secondary intervention) reduces CHD mortality and morbidity; meta-analysis of different studies shows that this decrease is proportional to the reduction of the LDL-C (Ross et al., Arch. Intern. Med. 159,1999, 1793-1802).

The clinical advantage of cholesterol lowering is greater for patients with pre- established CHD than for asymptomatic persons with hypercholesterolemia. According to current guidelines, cholesterol lowering treatment is recommended for patients who had survived a myocardial infarct or patients suffering from angina pectoris or another atherosclerotic disease, with a target LDL-C level of 100 mg/dl.

Preparations such as bile acid sequestrants, fibrates, nicotinic acid, probucol as well

as statins, i. e. HMG-Co-A reductase inhibitors such as simvastatin and atorvastatin, are used for usual standard therapies. The best statins reduce plasma LDL-C effectively by at least 40%, and also plasma triglycerides, a synergistic risk factor, but less effectively. In contrast, fibrates reduce plasma triglycerides effectively, but not LDL-C. Combination of a statin and a fibrate proved to be very efficacious in lowering LDL-C and triglycerides (Ellen and McPherson, J. Cardiol. 81,1998, 60B-65B), but safety of such a combination remains an issue (Shepherd, Eur. Heart J. 16,1995, 5-13). A single drug with a mixed profile combining effective lowering of both LDL-C and triglycerides would provide additional clinical benefit to asymptomatic and symptomatic patients.

In humans, statins are well tolerated at standard dosage, but reductions in non-sterol intermediates in the cholesterol synthesis pathway, such as isoprenoids and coenzyme Q, may be associated with adverse clinical events at high doses (Davignon et al. , Can. J.

Cardiol. 8,1992, 843-864; Pederson and Tobert, Drug Safety 14,1996, 11-24).

This has stimulated the search for, and development of compounds that inhibit cholesterol biosynthesis, yet act distal to the synthesis of these important, non-sterol intermediates. 2,3-oxidosqualene : lanosterol cyclase (OSC), a microsomal enzyme, represents a unique target for a cholesterol-lowering drug (Morand et al., J. Lipid Res. , 38, 1997,373-390 ; Mark et al. , J. Lipid Res. 37,1996, 148-158). OSC is downstream of farnesyl-pyrophosphate, beyond the synthesis of isoprenoids and coenzyme Q. In hamsters, pharmacologically active doses of an OSC inhibitor showed no adverse side- effects, in contrast to a statin which reduced food-intake and body weight, and increased plasma bilirubin, liver weight and liver triglyceride content (Morand et al., J. Lipid Res., 38,1997, 373-390). The compounds described in European Patent Application No. 636 367, which inhibit OSC and which lower the total cholesterol in plasma, belong to these substances.

OSC inhibition does not trigger the overexpression of HMGR because of an indirect, negative feed-back regulatory mechanism involving the production of 24 (S), 25- epoxycholesterol (Peffley et al. , Biochem. Pharmacol. 56,1998, 439-449; Nelson et al., J.

Biol. Chem. 256,1981, 1067-1068; Spencer et al., J. Biol. Chem. 260,1985, 13391-13394; Panini et al., J. Lipid Res. 27,1986, 1190-1204; Ness et al., Arch. Biochem. Biophys. 308, 1994,420-425). This negative feed-back regulatory mechanism is fundamental to the concept of OSC inhibition because (i) it potentiates synergistically the primary inhibitory effect with an indirect down-regulation of HMGR, and (ii) it prevents the massive accumulation of the precursor monooxidosqualene in the liver. In addition, 24 (S), 25- epoxycholesterol was found to be one of the most potent agonists of the nuclear receptor LXR (Janowski et al. , Proc. Natl. Acad. Sci. USA, 96,1999, 266-271). Considering that 24 (S), 25-epoxycholesterol is a by-product of inhibition of OSC it is hypothesized that the

OSC inhibitors of the present invention could also indirectly activate LXR-dependent pathways such as (i) cholesterol-7alpha-hydroxylase to increase the consumption of cholesterol via the bile acid route, (ii) expression of ABC proteins with the potential to stimulate reverse cholesterol transport and increase plasma HDL-C levels (Venkateswaran et al. , J. Biol. Chem. 275,2000, 14700-14707; Costet et al. , J. Biol. Chem. June 2000, in press; Ordovas, Nutr Rev 58,2000, 76-79, Schmitz and Kaminsky, Front Biosci 6,2001, D505-D514), and/or inhibit intestinal cholesterol absorption (Mangelsdorf, XIIth International Symposium on Atherosclerosis, Stockholm, June 2000). In addition, possible cross talks between fatty acid and cholesterol metabolism mediated by liver LXR have been hypothesized (Tobin et al. , Mol. Endocrinol. 14,2000, 741-752).

The present compounds of formula I inhibit OSC and therefore also inhibit the biosynthesis of cholesterol, ergosterol and other sterols, and reduce the plasma cholesterol levels. They can therefore be used in the therapy and prophylaxis of hypercholesterolemia, hyperlipemia, arteriosclerosis and vascular diseases in general. Furthermore, they can be used in the therapy and/or prevention of mycoses, parasite infections, gallstones, cholestatic liver disorders, tumors and hyperproliferative disorders, e. g. hyperproliferative skin and vascular disorders. In addition, it has unexpectedly been found that the compounds of the present invention can also be of therapeutical use to improve glucose tolerance in order to treat and/or prevent related diseases such as diabetes. The compounds of the present invention further exhibit improved pharmacological properties compared to known compounds.

Scheme 1

Trans- (4-methylaminomethyl-cyclohexyl)-methanol (7-trans with A5, A6 = H; A9 = Me) can be obtained from trans- (4-hydroxymethyl-cyclohexylmethyl)-carbamic acid tert-butyl ester [U. S. (2000) US 6,022, 969 A] by treatment with lithium aluminium hydride in tetrahydrofuran between room temperature and the reflux temperature of the tetrahydrofuran (step g). Introduction of a tert-butoxycarbonyl protective function by treatment with di-tert-butyl-dicarbonate in methanol/triethylamine between-10°C and room temperature gives compound 8 (AS, A6 = H; A9 = Me) (step h). Compounds with variable alkyl groups A5, A6 and A9 are prepared from cyclohexane-1, 4-dicarboxylic acid mono alkyl esters, preferentially mono isopropyl esters, by first introduction of the first alkyl group A5 by conversion of the acid moiety in 1 into the corresponding acid chlorides and treatment with a di-alkyl cuprates in solvents like ether or tetrahydrofuran preferentially at-78°C (step a). Reductive amination of the ketones 2 with ammonium formiate and sodium cyanoborohydride in solvents like methanol or ethanol preferentially at room temperature then gives amines 4 with A6 equal H (step b). If the ketones 2 are treated with an alkyllithium reagent in the presence of titanium tetrachloride in ether as described in Tetrahedron 42 (11), 2931-2935 (1986), then tertiary alkohols 3 are formed (step c). The tertiary alkohols 3 are then reacted with trimethylsilylazide in the presence of

borontrifluoride etherate in a solvent like benzene to from the azides as described in Tetrahedron Letters 28 (51), 6513-6516 (1987); the azides are subsequently hydrogenated with hydrogen gas and e. g. a palladium catalyst in solvents like methanol, ethanol or tetrahydrofuran to the primary amines 4 (step d). Introduction of a tert-butoxycarbonyl protective function at the primary amino moiety of compounds 4 leads then to compounds 5 (step e). Compounds 5 can be N-alkylated at the primary tert- butoxycarbonyl protected amino function with an alkyl halide in the presence of a base like sodium hydride in a solvent like N, N-dimethylformamide or acetonitrile at temperatures between room temperature and 80°C to introduce substituents A9 ; after reduction of the ester function with e. g. lithium aluminium hydride in solvents like tetrahydrofuran at temperatures between-50°C and room temperature, the compounds 8 are obtained (step f). Compounds 8 are subsequently oxidized to the corresponding aldehydes 9 by using e. g. Swern conditions: oxalyl chloride/dimethylsulfoxide/triethylamine in dichloromethane,-78°C to room temperature (step i).

Scheme 2

[4- (Tert-butyl-dimethyl-silanyloxymethyl)-cyclohexyl]-methanol compounds 1 are prepared from the corresponding bis-hydroxymethyl cyclohexane derivatives by treatment with one equivalent of n-butyl lithium in tetrahydrofuran at-78°C followed by one equivalent of tert-butyl-dimethyl-chlorosilane at-65°C to room temperature. Mesylation of [4- (tert-butyl-dimethyl-silanyloxymethyl)-cyclohexyl]-methanols 1 (methanesulfonyl chloride in dichloromethane and triethylamine at 0-10°C) gives the corresponding methanesulfonates, which are treated with sodium cyanide in N, N-dimethylformamide at 80°C to give the cyano compounds 2 with A5, A6 equal to hydrogen (step a). Direct reduction of the cyano compounds 2 e. g. by hydrogenation with a platinum catalyst in acidic methanol gives the primary amines 5 with A5, A6, A7 and A8 equal to hydrogen and

without tert-butyl-dimethyl-silyl protective function (step b). Alternatively, alkyl groups A5 and/or A6 can be introduced into cyano compounds 2 by treatment with a base like potassium tert-butoxide or sodium hydride in solvents like tetrahydrofuran or 1,2- dimethoxyethane followed by addition of one or sequentially two different alkyl halides, a reaction preferentially performed between 0°C and 80°C. Mono and/or dialkyl cyano compounds 2 can be reduced to compounds 5 as described above (step b). Alternatively, cyano compounds 2 can be reacted with alkyl Grignard reagents in solvents like ether or tetrahydrofuran between 0°C and the reflux temperature of the solvent to form the corresponding alkyl ketones 3 (step c). Reductive amination of the ketones 3 with ammonium formiate and sodium cyanoborohydride in solvents like methanol or ethanol preferentially at room temperature followed by removal of the tert-butyl-dimethyl-silyl protective function with aqueous hydrofluoric acid in a water/acetonitrile mixture at room temperature gives amines 5 with A8 equal to H (step e). Treatment of ketones 3 with a second alkyl Grignard reagent under conditions similar to those just described gives tertiary alcohols 4 (step d). The tertiary alkohols 4 are then reacted with trimethylsilylazide in the presence of borontrifluoride etherate in a solvent like benzene to form the corresponding azide as described in Tetrahedron Letters 28 (51), 6513-6516 (1987) and the azide is hydrogenated with hydrogen gas and e. g. a palladium catalyst in solvents like methanol, ethanol or tetrahydrofuran to the primary amines 5 without tert-butyl- dimethyl-silyl protective function, which gets lost under the conditions of the azide formation (step f). Treatment of the amino-alcohols 5 first with di-tert-butyl-dicarbonate in dichloromethane in the presence of triethylamine followed by acetic anhydride and pyridine in dichloromethane gives the di-protected compounds 6 (step g). Compounds 6 can be N-alkylated at the primary tert-butoxycarbonyl protected amino function with an alkyl halide in the presence of a base like sodium hydride in a solvent like N, N- dimethylformamide or acetonitril at temperatures between room temperature and 80°C to introduce substituents A9 and give, after basic cleavage of the acetate function, the primary hydroxy compounds 7 (step h). The primary hydroxy compounds 7 can be oxidized subsequently to the corresponding aldehydes 8 by using e. g. Swern conditions: oxalyl chloride/dimethylsulfoxide/triethylamine in dichloromethane,-78°C to room temperature (step i).

Scheme 3 Aldehydes 1 undergo Wittig reactions with a variety of ylids. Thus, treatment with (benzyloxyalkyl or haloalkyl) triphenylphosphonium salts, e. g. 4-

(bromobutyl) triphenylphosphonium bromide or 3- benzyloxypropyl) triphenylphosphonium bromide, preferentially with finely milled potassium carbonate as base in solvents like 2-methyl-2-butanol or ter-amyl alcohol at temperatures between room temperature and the reflux temperature of the solvents, yields [4- (5-bromo- (E, Z)-pent-1-enyl)-cyclohexylalkyl]-alkyl-carbamic acid tert-butyl esters 2 or [4- (4-benzyloxy- (E, Z)-but-1-enyl)-cyclohexylalkyl]-alkyl-carbamic acid tert-butyl esters 5 (step a). Optionally, the double bond present can be reduced by hydrogenation leading to compounds 3 and 6 (step b and e). If a benzyloxy function has been present in the phosphonium salt and the corresponding olefin, then, the hydrogenolytic removal of the benzyl group reduces the double bond at the same time (step e). After removal of the tert-butoxycarbonyl protective function with acid (steps c and f), the corresponding amine compounds 4 and 7 are converted into compounds 8 and 9 carrying the NA9WAl0 groups by the following procedures (steps d and g): a) NA9WAl0 = Sulfonamides or carbamates: treatment with an aryl-sulfonyl chloride or with an aryl chloroformate preferentially in the presence of diisopropyl-ethylamine, potassium carbonate, tetrahydrofuran and water between-10°C and room temperature. b) NA9WAl0 = Thiocarbamates: The amines may be reacted with Al°OCSCI in solvents like dioxane, dichloromethane or tetrahydrofuran in the presence of a base like diisopropyl-ethylamine or aqueous potassium carbonate. c) NA9WA'0 = Ureas: The amines may be reacted with isocyanate in dioxane at room temperature. d) NA9WA'0 = Thioureas: The amines may be reacted with isothiocyanate in dioxane at room temperature. e) NA9WA'0 = Amides: The amines may be reacted with A°COCl/Huenigsbase in CH2Cl2, A'COOH/EDCI/DMAP (via formation of the symmetrical anhydride, and subsequent addition of the starting amine at-10 °C to room temperature) or alternatively with Al°COOH/EDCI/DMAP or A'°COOH/Huenig's base or NMM/EDCI/HOBT in DMF, dioxane or CH2CI2 at room temperature. f) NA9WAl0 = Sulfamides: The amines may be reacted with sulfamoyl chlorides in dioxane in the presence of an excess of triethylamine. The sulfamoyl chlorides can be prepared from A'NH2 and chlorosulfonic acid in CH2C12 at 0 °C to room temperature followed by reaction with PCl5 in toluene at 75 °C. Alternatively, the sulfamoyl chlorides can be synthesized in acetonitrile with Al°NH2 and sulfuryl chloride at 0 °C to 65 °C.

Compounds 9, which contain a hydroxy function, are converted into the corresponding methanesulfonates by treatment with methanesulfonyl chloride in dichloromethane and triethylamine at 0-10°C (step h).

Amination of halides 8 and methanesulfonates 10 with amines AlA2NH is preferentially being performed in N, N-dimethylacetamide or in N, N-dimethylformamide, between room temperature and 80°C, or in methanol and optionally 1, 8-diazabicyclo [5. 4.0] undec- 7-ene at room temperature to reflux and yields the final amine compounds 11 (q = 1 or 2) (step i). Amines 11 may optionally be converted into a salt or into the N-oxides using a mixture of hydrogen peroxide urea adduct and phthalic anhydride in dichloromethane at room temperature. In case ALAUN (U absent) signifies imidazol-1-yl, then the transformation of halides 8 and methanesulfonates 10 is performed with imidazole, sodium hydride in a solvent like N, N-dimethylformamide preferentially at temperatures between 0°C and room temperature. If Al = H, heteroaromatic moieties A'may be introduced into compounds 11 by treatment with halo heteroaromatics in the presence of Huenig's base in N, N-dimethylformamide between room temperature and 100°C (Ger.

Offen. (1990), DE3905364 A1). Alternatively, Buchwald conditions e. g. Pd (OAc) 2,2- (Dicyclohexylphosphino) biphenyl, NaOtBu in toluene might be applied (John P. Wolfe, Hiroshi Tomori, Joseph P. Sadighi, Jingjun Yin, and Stephen L. Buchwald, J. Org. Chem., 65 (4), 1158-1174,2000).

Scheme 4

Primary alcohols 1 are treated with hydrogen chloride in dioxane at room temperature to remove the tert-butoxycarbonyl protective function; the primary or secondary amine thus formed then converted into groups NA9WAl0 as described in Scheme 3 (step a).

Conversion of the primary alcohols 2 into the corresponding methanesulfonate esters 3 is then performed as described above (step b). Transformation of methanesulfonates 3 into final compounds 4 is then performed as described in Scheme 3 (step c).

Aldehydes 5 react with (triphenyl-phosphoranylidene) -acetic acid esters in dichloromethane or toluene between room temperature and 110°C to the corresponding unsaturated ester compounds 6 (step d). Optionally, the double bond in the unsaturated ester compounds 6 can be hydrogenated using a palladium catalyst in a solvent like methanol or ethanol preferentially at room temperature (step e). Subsequently, the ester

function can be reduced using lithium aluminium hydride or diisobutyl aluminium hydride in tetrahydrofuran or 1,2-dimethoxyethane at temperatures between-78°C and the reflux temperature of the solvents giving the primary alcohol compounds 8 (step f).

Removal of the tert-butoxycarbonyl protective function with acid and treatment of the corresponding amine compounds as described in Scheme 3 gives the corresponding compounds 9 carrying groups NA9WAl0 (step g). The primary alcohol compounds 9 are then transformed into the corresponding methanesulfonate esters 10 as described above (step h), a process which leads to mixtures of methanesulfonate esters and chlorides or pure chlorides, if the double bond is still present. Transformation of methanesulfonate esters, mixtures of methanesulfonate esters and chlorides or pure chlorides 10 into final compounds 11 is then performed as described in Scheme 3.

Scheme 5

10 Aminoalkohols 1 can be protected a the amino-function e. g. by treatment with N- (benzyloxycarbonyloxy) -succinimide in methanol to give the Z-protected analogues 2 (step a). The Z-protected analogues 2 are subsequently oxidized to the corresponding aldehydes 3 by using e. g. Swern conditions: oxalyl chloride/dimethylsulfoxide/triethylamine in dichloromethane,-78°C to room temperature

(step b). Wittig reaction with (methoxymethyl) triphenylphosphonium chloride and potassium tert-butylate in tetrahydrofuran, preferentially between-10°C and room temperature, gives enol ethers 4 (step c) and after hydrolysis with 2N aqueous hydrochloric acid in tetrahydrofuran aldehydes 5 (step d). Reduction to the primary alcohols 6 with sodium borohydride in methanol followed by hydrolytic removal of the Z- protective function then leads to primary alcohols 7 (step e and f), which are converted into amino compounds 10 as described for aminoalkhols 7 in Scheme 3 (steps g, h, i).

Scheme 6 4- (Hydroxy-alkoxy)-benzoic acid esters 3 can be prepared from 4-hydroxy-benzoic acid esters 1 by various well known methods, e. g. Mitsunobu ether formation (diethyl-azo- dicarboxylate, triphenylphosphine in tetrahydrofuran between-10°C and the reflux temperature of the tetrahydrofuran) with a mono-benzyl protected dihydroxy-alkane (r = 2-8) and subsequent deprotection (hydrogenolysis with hydrogen gas and a palladium catalyst in methanol at room temperature) or by direct alkylation with a suitable bromo- or chloro-hydroxy alkane in the presence of a base like potassium carbonate in solvents like acetone, acetonitrile or N, N-dimethylformamide between room temperature and 100°C (steps a and b). Catalytic hydrogenation of 4- (hydroxy-alkoxy)-benzoic acid esters 3 using a rhodium catalyst and hydrogen gas at temperatures between room temperature and 80°C and pressures of hydrogen between normal pressure and 20 bar in solvents like ethanol or methanol and optionally a tertiary base like triethylamine gives mixtures of cis

and trans 4- (hydroxy-alkoxy)-cyclohexane carboxylic acid esters 4 with a strong preference for the cis isomers (step c). Isomerization to a cis/trans mixture close to 1 : 1 can be achieved after reintroduction of the benzyl group (e. g. with benzyl 2,2, 2-trichloro- acetimidate, trifluoroacetic acid in dichloromethane/cyclohexane at room temperature, step d) by quenching the enolate formed with lithium diisopropylamide at-78°C in tetrahydrofuran by treatment with methanol at the same temperature (step e). This mixture of cis and trans 4- (benzyloxy-alkoxy)-cyclohexane carboxylic acid esters 6 can be separated by chromatography into the pure cis and trans isomers 8 and 7 (step f).

Pure cis or trans 4- (benzyloxy-alkoxy)-cyclohexane carboxylic acid esters 1 can be converted into the corresponding N-alkyl amides 3 by well known procedures of saponification and amide formation via the corresponding acid chloride as intermediate (steps a and b). N-Alkyl amides 3 can then be reduced to the corresponding N-alkyl amines 4 with lithium aluminium hydride in tetrahydrofuran between room temperature and the reflux temperature of tetrahydrofuran (step c). Optionally, a tert-butoxycarbonyl protective function can be introduced with di-tert-butyl-dicarbonate as reagent before removal of the benzyloxy function (steps e and f). Compounds 5 with either a two carbon chain between cyclohexane ring and the amino function and/or substituents A5, A6, A7, A8 different from hydrogen are prepared from the carboxylic acid 2 as described in Schemes 1 and 2: i) the carboxylic acids 2 are modified in analogy to the procedures described for the carboxylic acids 1 in Scheme 1 ; or ii) the carboxylic acids 2 are reduced to the corresponding primary alcohol with borane-tetrahydrofuran complex in tetrahydrofuran between-10°C and the reflux temperature of tetrahydrofuran and then transformed in analogy to the procedures described for the hydroxy methyl compounds 1 in Scheme 2, leading to the primary amines 5 (step d). After introduction of a tert-butoxycarbonyl protective function into primary amines 4 and 5, the tert-butoxycarbonyl protected nitrogen function can be alkylated as described above leading to compounds 6 (step e).

Hydrogenolytic removal of the benzyl function and removal of the tert-butoxycarbonyl protective function under acidic conditions leads to cis or trans amino alcohol compounds 8 (steps f and g). Cis or trans amino alcohol compounds 8 are subsequently converted into analogues 9 carrying a group NA9WAI0 as described in Scheme 3 (step h). Conversion of the primary alcohols 9 into the corresponding methanesulfonate esters 10 is then performed as described above (step i). Transformation of methanesulfonate esters 10 into final compounds 11 is then performed as described in Scheme 3 (step k).

Scheme 8

Primary alcoholes 1 are reacted with 1, 4-dibromo-2-butene in a vigorously stirred mixture of dichloromethane and 50% w/w sodium hydroxide in the presence of tetrabutylammonium hydrogensulfate preferentially at room temperature to yield bromides 2 (step a). Transformation of bromides 2 into final compounds 3 is then performed as described in Scheme 3 (step b).

Primary alcohols 1 are converted to amines 4 by attaching the pre-assembled fragment A'AZNC (A3A4) (CH2) m-OH, which can be synthesized by known methods (step c): Primary alcohols 1 are first converted into the corresponding methanesulfonates ; fragments AIA2NC (A3A4) (CH2) m-OH are treated with sodium hydride in N, N-dimethylformamide at 0°C to room temperature, then, the methanesulfonates are added and the condensation performed between 0°C and 80°C to give amines 4. Alternatively, primary alcohols 1 are converted to the corresponding triflates (with trifluoromethansulfonic anhydride/2,6-di- tert-butylpyridine in dichloromethane at 0 °C). These triflates are then reacted in situ with alcohols AlA2NC (A3A4) (CH2) m-OH in the presence of 2, 6-di-tert-butylpyridine as base in nitromethane at room temperature to 60 °C to yield amines 4 [following a procedure of Belostotskii, Anatoly M.; Hassner, Alfred. Synthetic methods. 41. Etherification of hydroxysteroids via triflates. Tetrahedron Lett. (1994), 35 (28), 5075-6].

Scheme 9

Aldehydes 1 can be treated with triphenylphosphine, tetrabromomethane and triethylamine in dichloromethane at 0°C to room temperature to yield 2, 2-dibromo-vinyl derivatives 2 (step a). Rearrangement with n-buyl-lithium (ca 1.6 M in hexane) in tetrahydrofuran at-78°C, followed by reaction with formaldehyde (-78°C to room temperature) gives the propargyl alcohols 5 [step b and c; following conditions described

in: Marshall, James A.; Bartley, Gary S.; Wallace, Eli M. Total Synthesis of the Pseudopterane (-) -Kallolide B, the Enantiomer of Natural (+)-Kallolide B. J. Org. Chem.

(1996), 61 (17), 5729-5735; and Baker, Raymond; Boyes, Alastair L.; Swain, Christopher J.

Synthesis of talaromycins A, B, C, and E. J. Chem. Soc. , Perkin Trans. 1 (1990), (5), 1415- 21]. For longer side chains, the rearrangement is performed with n-butyl lithium (ca 1.6 M in hexane) in tetrahydrofuran at-78°C as above, followed by addition of a co-solvent such as 1, 3-dimethyl-3,4, 5,6-tetrahydro-2 (1H)-pyrimidinon and reaction with 0-protected co- bromo-alcohols 4 (s = 2-7) (step b and d; e. g. l-bromo-o)-tetrahydropyranyloxyalkane) to give after removal of the 0-protective function (e. g. with pyridinium p-toluenesulfonate in methanol at room temperature to 50°C) compounds 6. Conversion of compounds 5 and 6 into final compounds 8 can be performed as described in Scheme 3 (steps e and f).

The following tests were carried out in order to determine the activity of the compounds of formula I and their salts.

Inhibition of human liver microsomal 23-oxidosqualene-lanosterol cyclase (OSC) Liver microsomes from a healthy volunteer were prepared in sodium phosphate buffer (pH 7.4). The OSC activity was measured in the same buffer, which also contained 1mM EDTA and 1mM dithiothreitol. The microsomes were diluted to 0.8mg/ml protein in cold phosphate buffer. Dry [14C] R, S-monooxidosqualene (MOS, 12.8 mCi/mmol) was diluted to 20 nCi/l with ethanol and mixed with phosphate buffer-1% BSA (bovine serum albumin). A stock solution of 1 mM test substance in DMSO was diluted to the desired concentration with phosphate buffer-1% BSA. 40 ul of microsomes were mixed with 20 J. of the solution of the test substance and the reaction was subsequently started with 20 gel of the [14C] R, S-MOS solution. The final conditions were: 0.4mg/ml of microsomal proteins and 30 ptl of [14C] R, S-MOS in phosphate buffer, pH 7.4, containing 0.5% albumin, DMSO <0. 1% and ethanol <2%, in a total volume of 80 1.

After 1 hour at 37°C the reaction was stopped by the addition of 0.6 ml of 10% KOH-methanol, 0. 7ml of water and O. lml of hexane : ether (1: 1, v/v) which contained 25 Stg of non-radioactive MOS and 25 itg of lanosterol as carriers. After shaking, 1 ml of hexane: ether (1 : 1, v/v) was added to each test tube, these were again shaken and then centrifuged. The upper phase was transferred into a glass test tube, the lower phase was again extracted with hexane: ether and combined with the first extract. The entire extract was evaporated to dryness with nitrogen, the residue was suspended in 50 u. I of hexane: ether and applied to a silica gel plate. Chromatographic separation was effected in hexane: ether (1 : 1, v/v) as the eluent. The Rf values for the MOS substrate and the lanosterol product were 0.91 and, respectively, 0.54. After drying, radioactive MOS and lanosterol were observed on the silica gel plate. The ratio of MOS to lanosterol was determined from the radioactive bands in order to determine the yield of the reaction and OSC inhibition.

The test was carried out on the one hand with a constant test substance concentration of 100nM and the percentage OSC inhibition against controls was calculated. The more preferred compounds of the present invention exhibit inhibitions larger than 50%. In addition, the test was carried out with different test substance concentrations and subsequently the ICso value was calculated, i. e. the concentration required to reduce the conversion of MOS into lanosterol to 50% of the control value. The preferred compounds of the present invention exhibit ICso values of 1 nM to 10 uM, preferrably of 1-100 nM.

The compounds of formula I and/or their pharmaceutically acceptable salts can be used as medicaments, e. g. in the form of pharmaceutical preparations for enteral, parenteral or topical administration. They can be administered, for example, perorally, e. g. in the form of tablets, coated tablets, dragees, hard and soft gelatine capsules, solutions, emulsions or suspensions, rectally, e. g. in the form of suppositories, parenterally, e. g. in the form of injection solutions or infusion solutions, or topically, e. g. in the form of ointments, creams or oils. Oral administration is preferred.

The production of the pharmaceutical preparations can be effected in a manner which will be familiar to any person skilled in the art by bringing the described compounds of formula I and/or their pharmaceutically acceptable salts, optionally in combination with other therapeutically valuable substances, into a galenical administration form together with suitable, non-toxic, inert, therapeutically compatible solid or liquid carrier materials and, if desired, usual pharmaceutical adjuvants.

Suitable carrier materials are not only inorganic carrier materials, but also organic carrier materials. Thus, for example, lactose, corn starch or derivatives thereof, talc, stearic acid or its salts can be used as carrier materials for tablets, coated tablets, dragees and hard gelatine capsules. Suitable carrier materials for soft gelatine capsules are, for example, vegetable oils, waxes, fats and semi-solid and liquid polyols (depending on the nature of the active ingredient no carriers might, however, be required in the case of soft gelatine capsules). Suitable carrier materials for the production of solutions and syrups are, for example, water, polyols, sucrose, invert sugar and the like. Suitable carrier materials for injection solutions are, for example, water, alcohols, polyols, glycerol and vegetable oils.

Suitable carrier materials for suppositories are, for example, natural or hardened oils, waxes, fats and semi-liquid or liquid polyols. Suitable carrier materials for topical preparations are glycerides, semi-synthetic and synthetic glycerides, hydrogenated oils, liquid waxes, liquid paraffins, liquid fatty alcohols, sterols, polyethylene glycols and cellulose derivatives.

Usual stabilizers, preservatives, wetting and emulsifying agents, consistency- improving agents, flavour-improving agents, salts for varying the osmotic pressure, buffer substances, solubilizers, colorants and masking agents and antioxidants come into consideration as pharmaceutical adjuvants.

The dosage of the compounds of formula I can vary within wide limits depending on the disease to be controlled, the age and the individual condition of the patient and the mode of administration, and will, of course, be fitted to the individual requirements in each particular case. For adult patients a daily dosage of about 1 to 1000 mg, especially

about 1 to 100 mg, comes into consideration. Depending on severity of the disease and the precise pharmacokinetic profile the compound could be administered with one or several daily dosage units, e. g. in 1 to 3 dosage units.

The pharmaceutical preparations conveniently contain about 1-500 mg, preferably 1-100 mg, of a compound of formula I.

The following Examples serve to illustrate the present invention in more detail. They are, however, not intended to limit its scope in any manner.

Examples General remarks All reactions were performed under argon.

Example 1 1.1 2.90 g (11.0 mmol) trans- (4-hydroxymethyl-cyclohexylmethyl)-carbamic acid tert-butyl ester [U. S. (2000) US 6,022, 969 A] dissolved in 15 ml of tetrahydrofuran were added slowly to a suspension of 0.92 g of lithium aluminium hydride in 10 ml of tetrahydrofuran.

The reaction mixture was then stirred at 50°C for 4 hours, cooled to 0°C, treated with 2 g of ice, stirred at room temperature for 30 min. , diluted with ethyl acetate, dried over sodium sulfate, filtered and evaporated. Thus, crude trans- (4-methylaminomethyl- cyclohexyl) -methanol was obtained [MS: 158 (MHt)], which was dissolved in 20 ml of methanol, cooled to-10°C and treated at once with 2.77 g di-tert-butyl-dicarbonate. Then, the reaction mixture was stirred at-10°C for 30 min. and at room temperature for 1 hour.

Subsequently, 5 ml of water and 5 ml of triethylamine were added and the reaction mixture evaporated under reduced pressure. It was then poured into 100 ml of an ice/water mixture and extracted 3 times with 100 ml of dichloromethane. The combined dichloromethane phases were dried over magnesium sulfate and evaporated under reduced pressure. The residue formed was chromatographed on silica gel with a 1: 1 v/v mixture of dichloromethane and ethylacetate as the eluent giving 2.5 g (82%) trans- (4- hydroxymethyl-cyclohexylmethyl)-methyl-carbamic acid tert-butyl ester as colorless viscous oil, MS: 257 (M+).

1.2 0.45 ml of oxalyl chloride in 5.0 ml of dichloromethane were cooled to-78°C ; then, 0.41 g of dimethylsulfoxide in 2.0 ml of dichloromethane were slowly added and the reaction mixture stirred at-78°C for 10 minutes. Then, 0.680 g (2.64 mmol) trans- (4- hydroxymethyl-cyclohexylmethyl) -methyl-carbamic acid tert-butyl ester dissolved in 5.0 ml of dichloromethane were added and the reaction mixture stirred at-78°C for 10 minutes. Subsequently, 1.84 ml of triethylamine were added at the same temperature, the reaction mixture stirred 30 minutes at-78°C, warmed to room temperature and stirred for 1 hour. It was then poured into 50 ml of an ice/water mixture and extracted 3 times with 50 ml of dichloromethane. The combined dichloromethane phases were washed with dilute hydrochloric acid, sodium hydrogen carbonate solution and with water, dried over magnesium sulfate and evaporated under reduced pressure. The residue formed was chromatographed on silica gel with a 4: 1 v/v mixture of dichloromethane and ether as the

eluent giving 0.615 g (91.1%) trans- (4-formyl-cyclohexylmethyl)-methyl-carbamic acid tert-butyl ester as colorless amorphous solid, MS: 273 (MNH4+).

1.3 0.590 g (2.31 mmol) trans- (4-formyl-cyclohexylmethyl)-methyl-carbamic acid tert-butyl ester, 1.325 g (2.77 mmol) 4- (bromobutyl) triphenylphosphonium bromide and 1.28 g (9.24 mmol) potassium carbonate were suspended in 10 ml of tert-amyl alcohol and the reaction mixture heated at reflux for 2 hours. It was then cooled to room temperature, diluted with ethyl acetate, filtered and evaporated under reduced pressure. The residue formed was chromatographed on silica gel with a 95: 5 v/v mixture of dichloromethane and ether as the eluent giving 0.635 g (73.4%) trans-E/Z- [4- (5-bromo-pent-1-enyl)- cyclohexylmethyl]-methyl-carbamic acid tert-butyl ester as colorless viscous oil, MS: 373 (M+, lBr).

1.4 1.15 g (3.07 mmol) trans-E/Z- [4- (5-bromo-pent-1-enyl)-cyclohexylmethyl]-methyl- carbamic acid tert-butyl ester dissolved in 15 ml of ethanol were added to a suspension of 300 mg platinum dioxide freshly reduced to platinum by hydrogenation immediately prior to use. Hydrogenation was then continued at ambient pressure until 95% of the calculated amount of hydrogen had been consumed. Then, the reaction mixture was filtered over celite and evaporated giving 0.950 g (82%) trans- [4- (5-bromo-pentyl)-cyclohexylmethyl]- methyl-carbamic acid tert-butyl ester as colorless viscous oil, MS: 375 (M+, lBr).

1.5 0.950 g (2.52 mmol) trans- [4- (5-bromo-pentyl)-cyclohexylmethyl]-methyl-carbamic acid tert-butyl ester were dissolved in 6 ml of 4 N hydrogen chloride solution in dioxane and the reaction mixture stirred at room temperature for 4 hours. It was then evaporated under reduced pressure, re-suspended in tert-butyl methyl ether and filtered. There were thus obtained 0.724 g (91.7%) trans- [4- (5-bromo-pentyl)-cyclohexylmethyl]-methyl- amine hydrochloride as colorless amorphous solid, MS: 276 (MH+, 1Br).

1.6 0.786 ml Diisopropyl-aethylamine, 0.619 g (2.53 mmol) 4-trifluoromethyl-benzene sulfochloride and 0.952 mg potassium carbonate (dissolved in the minimal amount of water) were added to a solution of 0.718 g (2.30 mmol) trans- [4- (5-bromo-pentyl)- cyclohexylmethyl]-methyl-amine hydrochloride in 15.0 ml of tetrahydrofuran kept at - 10°C. The reaction mixture was then intensively stirred for 1 hour at-10°C and for 1 hour at room temperature. It was subsequently evaporated, poured into 50 ml of an ice/water mixture and extracted 3 times with 50 ml of dichloromethane.
