The lithium cation‐catalyzed direct reduction of allylic alcohols to alkenes using isopropanol as a hydride donor was developed. The hydride transfer of the in situ‐generated lithium isopropoxide to an allylic cation is the key process in this transformation. The reaction generates only water and acetone as byproducts, which highlights the synthetic utility of this method.

以异丙醇为还原剂直接还原烯丙醇

开发了使用异丙醇作为氢化物供体的锂阳离子催化的烯丙基醇直接还原为烯烃的方法。原位生成的异丙氧基锂向烯丙基阳离子的氢化物转移是该转化过程中的关键过程。该反应仅产生水和丙酮作为副产物，这突出了该方法的合成效用。
