A novel gold-catalyzed intermolecular oxidation of o-ethynylanilines has been developed. A range of functionalized 3-oxyindoles are readily accessed by utilizing this strategy. Importantly, this gold-catalyzed oxidative process outcompetes the typical indole formation.
已经开发了新颖的金催化的邻乙炔基苯胺的分子间氧化。通过利用该策略,可以容易地获得一系列官能化的3-氧吲哚。重要的是,这种金催化的氧化过程胜过了典型的吲哚形成。
