Palladium‐Catalyzed (4+2) Annulations of Silacyclobutanes and Activated Ketones

Abstract

Presented herein is a palladium‐catalyzed (4+2) annulation reaction between silacyclobutanes and activated ketones, which features advantages of operation simplicity, broad substrate scope and good functionality tolerance. A diversity of oxasilacyclohexanes were straightforwardly constructed in high yields.
