Method for optical resolution of piperidine carboxylic acid derivative

摘要

A method for producing an optically active piperidine carboxylic acid derivative, which comprises subjecting a piperidine carboxylic acid derivative of the formula (1):wherein Z is a protecting group for the carboxyl group, to optical resolution by means of an optical resolution agent of the formula (2):wherein symbol * indicates that the designated carbon atom is asymmetric.
