A coupling reaction of N‐phenoxyacetamides with N‐tosylhydrazones or diazoesters through RhIII‐catalyzed CH activation is reported. In this reaction, ortho‐alkenyl phenols were obtained in good yields and with excellent regio‐ and stereoselectivity. Rh–carbene migratory insertion is proposed as the key step in the reaction mechanism.
的偶联反应Ñ -phenoxyacetamides与Ñ -tosylhydrazones或通过铑diazoesters III催化的Ç H被报道活化。在该反应中,获得了高收率的邻链烯基苯酚,并且具有出色的区域选择性和立体选择性。Rh-卡宾迁移插入被认为是反应机理中的关键步骤。
