Hydrosilylation of norbornene with trichlorosilane in the presence of palladium catalyst (0.01–0.1 mol %) coordinated with (R)-MOP ligand gave a quantitative yield of exo-2-trichlorosilylnorbornane, which was oxidized with hydrogen peroxide to give (1S,2S,4R)-exo-2-norbornanol in 96% ee. The similar hydrosilylation and oxidation of endo-5,6-dicarbomethoxy-2-norbornene, bicyclo[2.2.2]octene, and norbornadiene
