Production of L-4-phenyl-2-aminobutanoic acid by transamination

摘要

A process is described for producing L-4-phenyl-2-amino butanoic acid. The process comprises reacting 4-phenyl-2-oxobutanoic acid or an ester thereof with L-aspartic acid in the presence of transaminase enzyme to produce L-4-phenyl-2-aminobutanoic acid and oxaloacetate, and decarboxylating said oxaloacetate.
