研究了以邻苯二甲酰亚胺为电子受体, 以末端三甲基硅烷基的醚-聚N-苄基甘氨酸肽链为电子给体的化合物5a5f的光反应, 发展了新的合成环肽类化合物的方法. 末端三甲基硅烷基的醚-聚N-苄基甘氨酸肽链——邻苯二甲酰亚胺5a5f在甲醇溶剂中进行光反应, 经连续的单电子转移(SET)历程有效地合成了环肽类化合物6a6f. 所合成的环肽类化合物的结构经核磁共振谱、高分辨质谱、X光晶体衍射所确定.

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 5a5f in methanol led to efficient generation of cyclic peptide products 6a6f, 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.

Key words: single electron transfer (SET), photoyclization, cyclic peptide, phthalimide, N-trimethylsilylmethyl peptide electron donor
