Efficient silylation reactions of propargyl epoxides catalyzed by copper catalyst have been developed. Under mild reaction conditions, the tri- and tetrasubstituted functionalized allenols and alkenes could be selectively obtained in moderate to high yields via tuning the bases and solvents used in the reactions. This work provides straightforward and efficient approaches to the synthesis of multifunctionalized
已经开发了由铜催化剂催化的炔丙基环氧化物的高效甲硅烷基化反应。在温和的反应条件下,可以通过调节反应中使用的碱和溶剂,以中等至高收率选择性地获得三和四取代的官能化烯丙醇和烯烃。这项工作为从相同的炔丙基环氧化合物原料合成多官能化的2,3-烯醇和立体定义的烯烃提供了直接有效的方法。
