Patent ID: 7462722

Claim:
A process for producing optically active 3-quinuclidinol or a salt thereof which comprises reacting 3-quinuclidinone or a salt thereof with hydrogen in the presence of a basic compound, a complex of a transition metal in Groups 8 to 10 with an optically active bidentate ligand, and an optically active diamine, wherein the ligand is an optically active bisphosphine of formula (III): wherein, R 3 and R 4 are the same or different and each independently is a cyclopentyl group, a cyclohexyl group, an unsubstituted phenyl group, or a phenyl group substituted with one or more of an alkyl group, an alkoxy group or a halogen atom; R 5 , R 6 , R 7 , R 8 , R 9 and R 10 are the same or different and each independently is hydrogen, halogen, alkyl, alkoxy, acyloxy, haloalkyl or dialkylamino group; any two of R 5 , R 6 and R 7 may form a substituted or unsubstituted (poly)methylene chain or a substituted or unsubstituted (poly)methylenedioxy group; and any two of R 8 , R 9 and R 10 may form a substituted or unsubstituted (poly)methylene chain or a substituted or unsubstituted (poly)methylenedioxy group; provided that each of R 7 and R 10 is not a hydrogen atom.
