Rhodium-Catalyzed, Remote Terminal Hydroarylation of Activated Olefins through a Long-Range Deconjugative Isomerization

The Rh-catalyzed, remote terminal hydroarylation of active olefins at the C7-position of indoles and the ortho-position of indolines and anilines with the appropriate choice of a N-PtBu2 directing group through long-range deconjugative isomerization has been reported. This transformation not only overcomes the conjugate rule of Michael acceptors but also controls the positional selectivity of indoles, representing a significant advancement in both alkene isomerization and the C–H alkylation of indoles.
