Abstract

Official abstract text for this publication.

Provided is a catalyst for asymmetric reduction, which can be produced by a convenient and safe production method, has a strong catalytic activity, and has excellent stereoselectivity. The present invention relates to a ruthenium complex represented by the following formula (1): wherein R 1 represents an alkyl group or the like; Y represents a hydrogen atom; X represents a halogen atom or the like; j and k each represent 0 or 1; R 2 and R 3 each represent an alkyl group or the like; R 11 to R 19 each represent a hydrogen atom, an alkyl group or the like; Z represents oxygen or sulfur; n 1 represents 1 or 2; and n 2 represents an integer from 1 to 3, a method for producing the ruthenium complex, a catalyst for asymmetric reduction formed from the ruthenium complex, and methods for selectively producing an optically active alcohol and an optically active amine using the catalyst for asymmetric reduction.
