Visible-light-induced epoxidation of α,β-unsaturated ketones is a kind of important chemical transformations, which could be applied for the synthesis of epoxypropane derivatives. Here, an efficient aerobic photoepoxidation protocol was reported. Through decatungstate-mediated photocatalysis, the aerobic Epoxidations of α,β-unsaturated ketones proceed well, furnishing the desired product in moderate
可见光诱导的 α、β-不饱和酮是一种重要的化学转化,可用于环氧丙烷衍生物的合成。在此,报道了一种有效的有氧光环氧化方案。通过十钨酸盐介导的光催化,α、β-的有氧环氧化反应不饱和酮反应良好,在温和条件下以中等至良好的产率提供所需产物。该方法表现出良好的官能团耐受性,并提供了可靠、直接的方法来获取各种官能化唑类环氧丙烷化合物。
