New combinations of activated ester groupings with N-substituents are described for preparing activated esters of peptides which may be used for cyclization (to homodetic cyclic polypeptides). Various activated esters of glycyl-glycyl-DL-phenylalanine and glycyl-DL-phenylalanyl-glycine yield cyclo-glycyl-glycyl-DL-phenylalanyl-glycyl-glycyl-DL-phenylalanyl. These reactions present new examples for
