摘　　要：由于三元环结构在中间体、天然产品和药物的合成中发挥着重要作用,这使得开发新的策略以获得环丙烷已变得越来越重要。在此,我们提出了一种通过活性亚甲基化合物和芳基烯烃的分子间脱氢环化合成环丙烷的电催化方法。该电化学过程不需要化学氧化剂,允许从廉价和简单易得的原料中快速获得各种官能团化的环丙烷。The development of novel strategies to access cyclopropanes has become increasingly important due to the vital role of these three-membered ring structures in synthetic intermediates,natural products,and pharmaceuticals.Herein,we present an electrocatalytic method for the synthesis of cyclopropanes through intermolecular dehydrogenative annulation of active methylene compounds and arylalkenes.This electrochemical process requires no chemical oxi-dants,allowing for a speedy access to various functionalized cyclopropanes from inexpensive and readily available materials.
