In this work, an interesting procedure for the synthesis of α,β-unsaturated amides from aryl azides and alkenylaluminum reagent has been developed. With palladium as the catalyst and XPhos as the ligand under carbon monoxide pressure, the desired α,β-unsaturated amides were isolated in good to excellent yields with good functional group tolerance. Remarkably, this procedure also represents an example
在这项工作中,从芳基叠氮化物和链烯基铝试剂合成α,β-不饱和酰胺的有趣方法已经被开发出来。以钯为催化剂,以XPhos为配体,在一氧化碳压力下,以良好的收率和良好的官能度耐受性分离出所需的α,β-不饱和酰胺。值得注意的是,该程序也代表了向异氰酸酯中添加有机金属试剂以合成α,β-不饱和酰胺的例子。
