Process for producing D-4,4'-biphenylalanine alkyl ester or L-4,4'-biphenylalanine alkyl ester from DL-4,4'-biphenylalanine alkyl ester

摘要

In the present invention, DL-4,4'-biphenylalanine alkyl ester is optically resolved to a D-4,4'-biphenylalanine alkyl ester or L-4,4'- with chiral diaroyl tartaric acid as an optical resolution agent. The present invention relates to a method for producing a biphenylalanine alkyl ester.
