reduction–imine formation–intramolecular cyclization–oxidation for the general synthesis of a wide variety of biologically relevant N-polyheterocycles, such as quinoxaline- and quinoline-fused derivatives, and phenanthridines, is reported. A simple, easily available, and environmentally friendly dioxomolybdenum(VI) complex has proven to be a highly efficient and versatile catalyst for transforming a
据报道,催化多米诺还原-亚胺形成-分子内环化-氧化用于一般合成各种生物学相关的N-多杂环,例如喹喔啉和喹啉稠合衍生物以及菲啶。一种简单、易得且环保的二氧代钼(VI)络合物已被证明是一种高效且多功能的催化剂,可用于转化涉及多种氧化还原过程的各种起始硝基芳烃。这不仅是一种可持续、步骤经济且耐空气和耐湿的方法,而且值得强调的是,序列第一步中产生的废物副产物被回收并合并到最终的目标分子中,从而改善了整体合成效率。此外,选定的吲哚喹喔啉在环己烷和甲苯中进行了光物理表征,烷基衍生物的荧光量子产率高于 0.7。
