We report herein a regio‐ and stereoselective photocatalytic hydrogenolysis of allylic alcohols to form unsaturated hydrocarbons employing a palladium(II)‐loaded titanium oxide; the reaction proceeds at room temperature under light irradiation without stoichiometric generation of salt wastes. Olefin and saturated alcohol moieties tolerated the reaction conditions. Hydrogen atoms were selectively incorporated
我们在此报告了一种利用钯(II)负载的二氧化钛对烯丙基醇进行区域和立体选择性光催化氢解反应以形成不饱和烃的方法。该反应在室温下在光照射下进行,而不会产生化学计量的盐废物。烯烃和饱和醇部分耐受反应条件。将氢原子选择性地掺入到烯丙基官能团的较少空间拥挤的碳中。该规程允许通过避免其他必要的保护/脱保护步骤从(R)-(-)-香芹酮短程合成(S)-(+)-lavandulol 。
