A novel visible light mediated cyclization of enol lactones with difluoroacyl arenes via a free radical tandem difluoroalkylation and C–C coupling of butenolides is presented. This strategy provides a facile approach to potential biological fluorinated γ-butyrolactones with excellent diastereoselectivity.
一种新颖的可见光介导的环化反应被介绍,该反应使用二氟代酰芳烃和烯醇内酯进行自由基串联二氟代烷基化和C-C偶联。该策略提供了一种简便的方法,制备具有优异对映选择性的潜在生物氟代γ-丁酸内酯。
