In the presence of tetrabutylammonium decatungstate and chiral spiro phosphoric acid, a light-mediated asymmetric C–H functionalization of unactivated hydrocarbons with exocyclic enones has been established. A wide range of cycloalkanes, benzylic, and allylic hydrocarbons are tolerated. This protocol proceeds via a hydrogen atom transfer/radical addition/hydrogen abstraction/enantioselective protonation
在存在四丁基癸酸铵和手性螺磷酸的情况下,已建立了具有光环烯酮的未活化烃的光介导的不对称C–H官能化。可以耐受各种环烷烃,苄基和烯丙基烃。该方案通过氢原子转移/自由基加成/氢提取/对映选择性质子化中继过程进行。
