Rhodium‐catalyzed Reaction of Silacyclobutanes with Unactivated Alkynes to Afford Silacyclohexenes

A Rh‐catalyzed reaction of silacyclobutanes (SCBs) with unactivated alkynes has been developed to form silacyclohexenes with high chemoselectivity. Good enantioselectivity at the stereogenic silicon center was achieved using a chiral phosphoramidite ligand. The resulting silacyclohexenes are useful scaffolds for synthesizing structurally attractive silacyclic compounds.
