The straightforward and efficient synthesis of indolo[2,1-a]isoquinoline derivatives has been achieved by the rhodium-catalyzed aerobic oxidative coupling/cyclization of 2-phenylindoles with alkynes. Some of the polycyclic products exhibit solid-state fluorescence.
吲哚[ 2,1- a ]异喹啉衍生物的直接有效合成是通过铑催化的2-苯基吲哚与炔烃的需氧氧化偶联/环化而实现的。一些多环产物表现出固态荧光。
