An efficient procedure for the copper-catalyzed cross-coupling between a broad range of cyanamides and iodoalkenes is reported. Upon reaction with catalytic amounts of copper(I) iodide and 2,2′-bisimidazole in the presence of cesium carbonate in DMF at 80 °C, a fast, regioselective, and stereoretentive cross-coupling occurs. This reaction, which was found to have a broad substrate scope, provides the
据报道,铜催化的广泛氰胺和碘代烯烃之间的交叉偶联的有效方法。在80℃下于碳酸铯中在碳酸铯存在下与催化量的碘化亚铜(I)和2,2'-双咪唑反应后,会发生快速,区域选择性和立体保持性交叉偶联。发现该反应具有广泛的底物范围,提供了N-链烯基氰酰胺的第一个一般入口,N-链烯基氰酰胺具有巨大的合成潜力。
