A range of non-natural dipeptides of the general formula D-(-)-phenylglycyl-L-X, where X is a natural α-amino acid, have been prepared by penicillin acylase-catalyzed synthesis in aqueous medium from D-(-)-phenylglycine amide and the corresponding amino acids. The conversion of the dipeptides to the corresponding dipeptide esters, followed by their subsequent spontaneous cyclization afforded the corresponding stereoisomerically pure diketopiperazines.
