Document Type and Number:
Japanese Patent JP5017098
Kind Code:
B2
Abstract:
Compounds of the formula (I) or (I′), where R1 is a hydrogen atom or C1-C4-alkyl and R′1 is C1-C4-alkyl; X1 and X2 are each, independently of one another, a secondary phosphine group; R2 is hydrogen, R01R02R03Si—, C1-C18.acyl substituted by halogen, hydroxy, C1-C8-alkoxy or R04R05N—, -or R06—X01—C(O)—; R01, R02 and R03 are each, independently of one another, C1-C12-alkyl, unsubstituted or C1-C4-alkyl or C1-C4-alkoxy-substituted C6-C10-aryl or C7-C12-aralkyl; R04 and R05 are each, independently of one another, hydrogen, C1-C12-alkyl, C3-C8-cycloalkyl, C6-C10-aryl or C7-C12-aralkyl, or R04 and R05 together are trimethylene, tetramethylene, pentamethylene or 3-oxapcntylene; R06 is C1-C18-alkyl, unsubstituted or C1-C4-alkyl- or C1-C4-alkoxy-substituted C3-C8-cycloalkyl, C6-C10-aryl or C7-C12-aralkyl; X01 is —O— or —NH—; T is C6-C20-arylene; v is 0 or an integer from 1 to 4; and * denotes a mixture of racemic or enantiomerically pure diastereomers or pure racemic or enantiomerically diastereomers, are excellent chiral ligands for metal complexes as enantioselective catalysts for the hydrogenation of prochiral organic compounds.
