A direct alkoxycarbonylation/cyclization reaction is accomplished under visible light-induced photoredox catalysis. With this approach, a variety of ester-substituted indolo[2,1-a]isoquinolines are prepared in good to excellent yields. It is worth noting that this method not only can afford the synthesis of indolo[2,1-a]isoquinolines but also can provide an alternative route for generating complex
在可见光诱导的光氧化还原催化下完成直接的烷氧羰基化/环化反应。使用这种方法,可以以良好至优异的产率制备多种酯取代的吲哚[2,1- a ]异喹啉。值得注意的是,该方法不仅可以合成吲哚[2,1- a ]异喹啉,还可以为生成带有羧酸酯的复杂目标结构提供替代途径。
