developed to synthesize 2,2-disubstituted indolin-3-ones under mild conditions. A series of nucleophiles have been added to the 2-arylindole-3-ones, generated in situ under metal-free electrochemical oxidative dearomatization of 2-arylindoles, to afford 2,2-disubstituted 3-carbonyl indoles with heteroquaternary centers in 57–79% yields.
开发了一种电化学方法,可在温和条件下合成 2,2-二取代二氢吲哚-3-酮。一系列亲核试剂已添加到 2-芳基吲哚-3-酮中,在 2-芳基吲哚的无金属电化学氧化脱芳构化下原位生成,得到 2,2-二取代的 3-羰基吲哚,在 57-79 中具有杂季中心% 产量。
