Precision indole skeletal editing for single-carbon replacement · L. Zhang et al.
原文开头
Ling Zhang1†, Yatao Lang1†, Zhen Luo1†, Xinlong Han1, Huiying Zeng1*, Chao-Jun Li2* Indole is widely present in pharmaceuticals and natural products. In this work, we report an intramolecular skeletal editing reaction of tryptamine derivatives enabled by photoreaction of a pendant amide that simultaneously achieves regioselective single-carbon replacement and substitution at the C2 position of indoles. This strategy facilitates deuteration, alkylation, arylation, and acylation at the indole C2 position while also enabling the incorporation of 13C-labeled carbon into the scaffold. We highlighted the practical applicability of this method through a concise four-step total synthesis of quebrachamine, a complex monoterpene indole alkaloid. …
