BF3·OEt2-catalyzed cascade cyclization reaction of vinyloxirane with coumarin is described, affording the benzocoumarin derivatives with moderate to excellent yields (72–92%). The reaction demonstrates exceptional substrate tolerance and has been extensively explored for its potential in drug development, including scale-up experiments, functional group transformations, and screening of the products for anticancer
描述了 BF 3 ·OEt 2催化的乙烯基环氧乙烷与香豆素的级联环化反应,以中等至优异的收率 (72–92%) 提供苯并香豆素衍生物。该反应表现出卓越的底物耐受性,并因其在药物开发中的潜力而得到广泛探索,包括放大实验、官能团转化和产品抗癌活性筛选。此外,反应机制已通过中间捕获和控制实验得到严格验证。此外,该反应代表了不常见的非金属催化的乙烯基环氧乙烷分子间环化。
