ligand-assisted, Rh-catalyzed intramolecular alkenehydrosilylation of homoallylic silyl ethers (1) was developed to provide 1,3-trans-oxasilacyclopentanes (trans-2) in a highly regio- and diastereoselective manner. The modification of metal-ligand architecture employing an inner-sphere functional diene ligand (1,3-cyclohexadiene) and a supporting phosphine ligand (BINAP) was identified as responsible for
