Oxasilacyclopentanes 3, generated by either free-radical cyclisation, intramolecular hydrosilylation, or silicon tethered Diels-Alder reaction, may be efficiently opened with 2-propenyl-lithium and the product alcohols oxidised to prepare precursors 2 for silicon tethered ene cyclisation. Efficient and highly stereoselective ene reactions have been achieved with these precursors.
