摘要

The extremely low efficiency during the α-chymotrypsin-catalyzed coupling of an inherently poor amino acid substrate, eg, alanine, using the methyl ester as an acyl donor was significantly improved using esters such as the 2, 2, 2-trifluoroethyl or carbamoylmethyl ester. The ameliorating effect of the latter ester was especially significant.
