研究了以邻苯二甲酰亚胺为电子受体,以肽链为电子给体的新型分子内给受电子体系化合物1a1h在甲醇溶液中的光反应,发展了合成三环异吲哚酮并环肽类化合物的方法. 化合物1a1b 1d1h在甲醇溶液中经连续的光诱导单电子转移(SET)历程生成了三环异吲哚酮并环肽化合物2a2b 2d2h. 所有新化合物的结构均经核磁共振谱、高分辨质谱所确定.

Exploratory photochemical studies on phthalimido-polypeptides 1a1h in which phthalimides worked as light absorbance acceptors and polypeptide served as electron donor centers have been conducted, leading to the development of synthetic methodology to construct tricyclic isoindole cyclopeptide mimetics. It was found that irradiation on 1a, 1b, 1d1h in methanol led to efficient generation of tricyclic isoindole cyclic peptides 2a, 2b, 2d2h, which may be through sequential single electron transfer (SET) pathway. The structures of new compounds were determined by NMR and HRMS spectroscopy.

Key words: photoreaction, single electron transfer (SET), cyclic peptide, phthalimide, tricyclic isoindole cyclic peptide
