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

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.
