A rhodium(III)-catalyzed domino annulation of simple olefins with diazo oxindoles to give spirooxindole pyrrolone products is described. This reaction can be formally viewed as the result of an anomalous tandem C-H activation, carbene insertion, Lossen rearrangement, and a nucleophilic addition process. The potential utility of this reaction was further demonstrated by the late-stage diversification
描述了铑(III)催化的简单烯烃与重氮恶吲哚的多米诺环化反应,以得到螺恶吲哚吡咯烷酮产物。可以将这种反应正式地看做是异常串联CH活化,卡宾插入,洛森重排和亲核加成过程的结果。药物分子的后期多样化进一步证明了该反应的潜在效用。
