A nickel‐catalyzed Heck cyclization for the construction of quaternary stereocenters is reported. This transformation is demonstrated in the synthesis of 3,3‐disubstituted oxindoles, which are prevalent motifs seen in numerous biologically active molecules. The method shows broad scope, proceeds in synthetically useful yields, and provides a rare means to construct stereochemically complex frameworks
据报道,镍催化的Heck环化反应可用于构建四元立体中心。3,3-二取代的羟吲哚的合成证明了这种转化,这是在许多生物活性分子中常见的基序。该方法具有广阔的应用前景,可以合成获得有用的收率,并且为通过非贵金属催化构建立体化学复杂的骨架提供了一种难得的手段。
