Title:
NOVEL CHIRAL PHASE-TRANSFER CATALYST, AND METHOD FOR PREPARING Α-AMINO ACID BY USING SAME
Document Type and Number:
WIPO Patent Application WO/2017/200184
Kind Code:
A1
Abstract:
The present invention relates to a novel chiral phase-transfer catalyst, and a method for preparing an α-amino acid by using the same. According to the present invention, an α-amino acid could be chirally synthesized in a high yield under an easy industrially applicable reaction condition by using a novel cinchona alkaloid compound as a chiral phase-transfer catalyst, and thus the present invention can be used as a key technique of the α-amino acid synthesis and preparation field.
