Enantioselective syntheses O 0031Asymmetric Ring Opening of meso-Epoxides Catalyzed by the Chiral Phosphine Oxide BINAPO. -Bis(phosphine oxide) (S)-BINAPO is an effective catalyst for the synthesis of chlorohydrins from meso-epoxides and tetrachlorosilane. Since the presence of iPr2NEt in the reaction of stilbene oxide dramatically enhances the enantioselectivity, these conditions are also applied to the other epoxides (I) and (III). -(TOKUOKA, E.; KOTANI, S.; MATSUNAGA, H.; ISHIZUKA, T.; HASHIMOTO, S.; NAKAJIMA*, M.; Tetrahedron: Asymmetry 16 (2005) 14, 2391-2392; Fac.
