Optically active cyclic alcohol compound
Abstract:
The present invention relates to a method for preparing an optically active cyclic alcohol compound represented by general formula [I]: [wherein R represents a hydrogen atom or a protecting group for amino group, and * represents an asymmetric carbon atom.] which comprises a step of subjecting a cyclic ketone compound represented by general formula [II]: [wherein R has the same meaning as defined above.] to asymmetric reduction (A) in the presence of an optically active oxazaborolidine compound and a boron hydride compound, or (B) in the presence of an asymmetric transition metal complex obtained from a transition metal compound and an asymmetric ligand and a hydrogen donor, and relates to said compound.
