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.
