The D-D, L-L, D-L and L-D stereomers of both valyllysine anhydride and phenylalanyllysine anhydride, and the D-L and L-L stereomers of both valylornithine anhydride and phenylalanylornithine anhydride, have been synthesized in order to compare them with the cyclic peptide antibiotics, with which they possess several structural features in common. Synthesis has been achiveved by the dicyclohexylcarbodiimide-induced
