A relay photoredox catalysis strategy concomitant with [1,5] hydrogen atom transfer has been applied in the construction of a biologically important indolo[2,1-a]isoquinoline framework via a cascade reaction. This reaction enables double C(sp3)–H bond functionalization and formation of two carbon–carbondouble bonds from readily available starting materials in an efficient and step-economical manner
与[1,5]氢原子转移相伴的继发性光氧化还原催化策略已通过级联反应用于构建具有重要生物学意义的吲哚[2,1- a ]异喹啉骨架。该反应可实现双C(sp 3)-H键官能化,并以有效和分步经济的方式从容易获得的起始原料中形成两个碳-碳双键。
