An efficient and environmentally benign Cu-mediated method was developed for direct cascade C–H/N–H annulation to construct polyheterocyclic indoloquinoline scaffolds. This method highlights an emerging strategy for transforming inert C–H bonds into versatile functional groups in organic synthesis and provides a new versatile approach for the efficient synthesis of indolo[3,2-c] and [2,3-c]quinoline
开发了一种高效且环境友好的铜介导的方法,用于直接级联C–H / N–H环化,以构建多杂环吲哚并喹啉支架。该方法突出了在有机合成中将惰性C–H键转变为通用官能团的新兴策略,并为有效合成吲哚[3,2- c ]和[2,3- c ]喹啉生物碱提供了新的通用方法。
