Benzylglycine was used as starting material for the synthesis of N-(amidosilane teminated polybenzylglycine peptide chain)phthalimide (1). Irradiating methanol solution containing 1 is observed to promote formation of biradical 10. Then the biradical 10 copulates to give cyclopolyglypeptides 2 in high yield and high selectivity. The structures of all the new compounds were characterized by MS and NMR techniques.

Key words: photoinduced, single electro transfer, cyclic peptide compound, synthesis
