Method of producing alpha -L-aspartyl-L-phenylalanine methylesters

摘要

A method for the preparation of alpha -L-aspartyl-L-phenylalanine methylester, which method comprises reacting an ester of L-phenylalanine with N and alpha -carboxyl-protected L-aspartic acid, to produce an alpha -L-aspartyl-L-phenylalanine methylester without racemization and isomer formation and in high yields.
