Title:
OPTICAL RESOLVER, PROCESS FOR PRODUCING OPTICALLY ACTIVE ISOMER, AND 1,5-SUBSTITUTED BICYCLO[3.3.0]-2-OXAOCTANE COMPOUND
Document Type and Number:
WIPO Patent Application WO/2005/080300
Kind Code:
A1
Abstract:
An optical resolver comprising a bicycle[3.3.0]-2-oxaoctane compound represented by the formula [1], [2], or [3]; a process for producing an optically active isomer which comprises reacting the optical resolver with a mixture of optically active monomers having active hydrogen to obtain a diastereomer mixture, separating the diastereomer mixture into the diasteromers, and then decomposing either of these to obtain an optically active (R) or (S) isomer; and the compound in which R11 is fluorenylmethyl, fluorenylidenemethyl, bis(4-cyclohexylphenyl)methyl, 4-(9-phenanthryl)phenyl, 4-(1-pyrenyl)phenyl, 4-(5-acenaphthenyl)phenyl, or 4-(9-anthryl)phenyl. Use of the optical resolver enables an optically active isomer which has an extremely high purity and is useful to be efficiently produced.
