Application of regioselective remote photocyclization of a pair system consisting of a phthalimide group and a methylthio group to a homologous series of N-substituted phthalimides (4 and 5) possessing a terminal sulfide function in the amide side chain was investigated. On irradiation, medium to large membered cyclic peptide-like compunds (6, 7 and 9), up to a thirty-eight membered ring product (6f), were synthesized in moderate yields.
研究了由邻苯二甲酰亚胺基团和甲硫基团组成的偶对体系的区域选择性远程光环化应用于一系列具有末端硫化物功能的N-取代邻苯二甲酰亚胺(4和5)。在照射下,合成了中至大环肽类化合物(6、7和9),最高可达三十八元环产物(6f),产率适中。
