英文摘要：

Exploratory photochemical studies on trimethylsilyl-terminated phthalimide-ether-N-benzylpolyglycines in which phthalimides worked as light absorbance acceptors and ether-N-（trimethylsilyl）methylamides served as electron donor centers have been conducted, leading to the development of new synthetic methodology to construct cyclic polypeptide mimetics. It was found that irradiation on trimethylsilyl-terminated phthalimide-ether-poly-N-benzylglycine 5a-5f in methanol led to efficient generation of cyclic peptide products 6a-6f, which may be through sequential single electron transfer （SET） pathway. The structures of these cyclic peptide products were determined by NMR and HRMS spectroscopy as well as fully characterized by X-ray crystallography.
