A simple modular tandem approach to multiply substituted cyclopentane derivatives is reported, which succeeds by joining organometallic addition, conjugate addition, radical cyclization, and oxygenation steps. The key steps enabling this tandem process are the thus far rarely used isomerization of allylic alkoxides to enolates and single‐electron transfer to merge the organometallic step with the radical
报道了一种简单的模块化串联方法来多重取代的环戊烷衍生物,该方法通过加入有机金属加成,共轭加成,自由基环化和氧合步骤而成功。实现这种串联过程的关键步骤是迄今很少使用的烯丙基醇盐异构化为烯醇化物和单电子转移以将有机金属步骤与自由基和氧合化学结合在一起。多种电子对比反应性中间体的受控产品组合使人们能够从非常简单且容易获得的商品前体中广泛获得高度官能化的环戊烷衍生物。筛选了合成化合物的抗病毒活性,许多化合物显示出对丙型肝炎病毒和登革热病毒的有效活性。
