A highly efficient and facile cobalt-catalyzed C–H activation and peroxidation of 2-oxindoles was reported, which provides a new pathway for the synthesis of biologically active 3-peroxy-2-oxindoles from readily available starting materials in excellent chemical yields. The resulting products could be further transformed into various substituted 3-peroxyoxindoles in good to excellent yields. The developed
据报道,一种高效且容易的钴催化的2-氧吲哚的C–H活化和过氧化反应,为从易于获得的起始原料以优异的化学收率合成具有生物活性的3-过氧-2-氧吲哚提供了一条新途径。可以将所得产物以良好至优异的产率进一步转化为各种取代的3-过氧羟吲哚。所开发的方法已成功应用于天然产物(±)-N- [2-(3-羟基-2-氧代-2,3-二氢-1 H-吲哚-3-基)乙基]乙酰胺的合成。
