The superiority of the carbamoylmethyl ester as an acyl donor for the α-chymotrypsin-catalysed segment condensations via the kinetically controlled approach is demonstrated in several model systems carried out in organic media with low water content. Furthermore, this approach is successfully applied to the construction of the Leu-enkephalin sequence via a 4 + 1 segment coupling.

The coupling efficiency in α-chymotrypsin-catalysed peptide synthesis is greatly improved by the use of activated esters such as the 2,2,2-trifluoroethyl ester as acyl donor instead of the conventional methyl ester; this approach is useful for the incorporation of non-protein amino acids into peptides.
