T. Miyazawa et al., alpha-Chymotrypsin-catalyzed enantioselective amidation of chiral amines using an N-protected amino acid carbamoylmethyl ester as acyl donor, BIOTECH LET, 21(9), 1999, pp. 725-728
alpha-Chymotrypsin catalyzed the highly enantioselective amidation of chira
l amines such as 1-(1-naphthyl)ethylamine using N-benzyloxycarbonyl-(S)-phe
nylalanine carbamoylmethyl ester as acyl donor (E = 25-660) in acetonitrile
with low water content.
