Rhodium(III)-Catalyzed Meta-Selective C-H Alkenylation of Phenol Derivatives

摘要

Rhodium(III)-catalyzed remote meta-selective C-H alkenylation of phenol derivatives has been developed using a traceless organosilicon template as the directing group. This transformation proceeds smoothly with good yields and high meta-selectivities toward a series of phenol and alkene substrates. In addition, this protocol provides an effective strategy for late-stage transformations of various meta-alkenylated aromatic compounds.
