[reaction: see text] A modified Edmandegradation procedure provides an effective means of introducing a heterocycle at the N-terminus of an alpha-amino acid amide or peptide. Reaction of a peptide with an isothiocyanate, followed by dehydrothiolative trapping of the intermediate thiourea, by intramolecular cyclization of the weakly nucleophilic adjacent amide nitrogen, generates an iminohydantoin

An economical, solvent-free, and metal-free method for peptidesynthesis via C–N bond cleavage using lactams has been developed. The method not only eliminates the need for condensation agents and their auxiliaries, which are essential for conventional peptidesynthesis, but also exhibits high atom economy. The reaction is versatile because it can tolerate side chains bearing a range of functional
