Title:
METHOD FOR PRODUCING OPTICALLY ACTIVE VALERIC ACID DERIVATIVES USING OPTICAL RESOLUTION BY ENZYME
Document Type and Number:
WIPO Patent Application WO/2017/155025
Kind Code:
A1
Abstract:
Provided is a method for producing compound (1) or (6) by optical resolution using a specific hydrolase. (In the formula, R represents a protecting group of a carboxy group, R1 and R2 each independently represent a hydrogen atom or a protecting group of an amino group.)
