Abstract
Disclosed is a method for preparing (S)-indoline-2-carboxylic acid and (S)-indoline-2-carboxylic acid methyl ester using an inexpensive industrially available enzyme capable of assuring superior optical purity and yield. At this time, the hydrolytic enzyme is selected from the group consisting of Savinase, Alcalase, Novozym 243, Everlase, Esperase, Protease 7 and Acylase, whereby (S)-indoline-2-carboxylic acid and methyl ester thereof having an optical purity of at least 99% e.e. can be obtained through a simplified preparation process, thus generating economic benefits.
