This work illustrates the reductive coupling of electron-richaryl halides with tertiary alkyl halides under Ni-catalyzed cross-electrophile coupling conditions, which offers an efficient protocol for the construction of all carbon quaternary stereogenic centers. The mild and easy-to-operate reaction tolerates a wide range of functional groups. The utility of this method is manifested by the preparation
这项工作说明了富电子芳基卤化物与叔烷基卤化物在 Ni 催化的交叉亲电偶联条件下的还原偶联,为构建所有碳四元立体中心提供了有效的方案。温和且易于操作的反应可耐受广泛的官能团。该方法的实用性通过环色胺衍生物的制备得到证明,其中成功掺入 7-吲哚基部分特别令人感兴趣,因为许多天然产物由这些关键支架组成。已经进行了 DFT 计算以研究提议的自由基链和双氧化加成途径,这为在溶液中发生的反应部分提供了有用的机理见解。
