A platinum-catalyzed intramolecular silaboration of borylsilanyl homoallyl ethers gave 1-oxa-2-silacyclopentanes in high yields. The stereoselectivity of the reactions strongly depended on the used ligands. A complementary synthesis of a pair of diastereomers of 6-methylheptane-1,3,5-triol is described.
