A straightforward synthesis of a tetrasubstituted halobutenolide, bromobeckerelide, was achieved by photosensitized oxygenation of a trisubstituted α-trialkylsilylfuran which was obtained by the introduction of desired substituents into a furan ring via regioselective lithiation.
四取代的卤代丁烯内酯溴贝克瑞德的直接合成是通过三取代的α-三烷基甲硅烷基呋喃的光敏氧化来实现的,该三取代的α-三烷基甲硅烷基呋喃是通过区域选择性锂化将所需的取代基引入呋喃环中获得的。
