diastereoselective hypervalent iodine-mediated 1,3-difluorination of homoallylic (aryl) ethers. The transformation proceeds through a transiently formed oxonium intermediate that is opened by fluoride to rearrange an alkyl chain. The protocol is scalable and tolerates a variety of functional groups and substitution on the alkenyl chain. Mechanistic studies reveal key insights into the reaction selectivity.
我们报道了高烯丙基(芳基)醚的非对映选择性高价碘介导的 1,3-二氟化。该转化通过瞬时形成的氧鎓中间体进行,该中间体被氟化物打开以重新排列烷基链。该协议具有可扩展性,可容忍烯基链上的各种官能团和取代。机理研究揭示了反应选择性的关键见解。
