α-chymotrypsin-catalysed peptide synthesis via the kinetically controlled approach is greatly improved by the use of activated esters such as the 2,2,2-trifluoroethyl ester as acyl donors instead of the conventional methyl ester in organic solvents such as acetonitrile with low water content. This approach is useful for the incorporation of non-protein amino acids such as halogenophenylalanines into peptides.
