with chloromethyl silicate as a methylene transfer reagent has been accomplished via visible‐light‐mediated redox‐neutral catalysis. This method features broad functional group tolerance and mild conditions. In addition to α‐substituted vinylphosphonates, a range of Michael acceptors including α,β‐unsaturated acrylate, ketone, amide and sulfone are suitable substrates for this photocatalytic cyclopropanation
通过可见光介导的氧化还原中性催化,完成了以
氯甲基
硅酸盐作为亚甲基转移试剂的烯烃
环丙烷化反应。该方法具有广泛的官能团耐受性和温和条件。除α-取代的
乙烯基膦酸酯外,包括此化合物的一系列迈克尔受体(包括α,β-不饱和
丙烯酸酯,酮,酰胺和砜)都是适用于这种光催化
环丙烷化的底物。还介绍了该方案在
