Rhodium(III)‐Catalyzed Cross Coupling of Sulfoxonium Ylides and 1,3‐Diynes to Produce Naphthol‐Indole Derivatives: An Arene ortho C−H Activation/Annulation Cascade

Abstract

AbstractSynthesis of naphthol‐indoles starting from easily available 1,3‐diynes and sulfoxonium ylides via RhIII‐catalyzed C−H activation/hydroamination cascade process in a one pot manner has been developed. The reaction proceeds through a RhIII‐catalyzed arene ortho C−H activation and silver‐catalyzed hydroamination cascade to afford a variety of C2 position functionalized indoles in good yields with broad substrate scope and good functional group tolerance.
