Rh(III)‐Catalyzed Chemodivergent Coupling of Sulfoxonium Ylides and Acryloyl Silanes

Abstract

A protocol of Rh(III)‐catalyzed C−H activation utilizing sulfoxonium ylides as traceless directing group and acryloyl silanes has been reported. This strategy provides an efficient and convenient method to construct the tricyclic skeleton of furan‐fused indanone by simultaneously constructing two C−C bonds and one C−O bond in one pot, featuring broad substrate scope. Moreover, the C−H alkenylation have been attained under controlled conditions.
