metal-catalyzed carbometallation of unsaturated hydrocarbons constitutes one of the most efficient synthetic methodologies for the construction of C—C bond. Recently, the incorporation of organometallic reagent with the CO gas as a nucleophilic acyl synthon could enable the acylmetallation reaction, which greatly increases the horizon of carbometallation chemistry. Herein, we report a nickel-catalyzed
过渡金属催化不饱和烃的碳金属化是构建CC键最有效的合成方法之一。最近,将有机金属试剂与CO气体结合作为亲核酰基合成子可以实现酰基金属化反应,这极大地拓展了碳金属化化学的视野。在此,我们报道了镍催化的邻氰基肉桂酸酯和邻氰基苯乙烯的区域发散酰基化反应,其中氰基部分在分子内捕获锌中间体以触发串联环化过程。该方案具有条件温和、底物范围广和优异的官能团耐受性的特点,从而提供了多种高度功能化的碳环化合物。
