    [reaction: see text] Expanding the scope of enantioselective catalysis via DKR, transfer hydrogenation of a variety of cyclic alpha-halo ketones was accomplished using the Noyori/Ikariya (R,R)- or (S,S)-I catalysts and either HCO(2)H/Et(3)N or HCO(2)Na/n-Bu(4)NBr in H(2)O/CH(2)Cl(2) as the hydrogen sources. Good yields of vicinal bromo-, chloro-, and fluorohydrins with excellent de and ee levels were

    A comparative study of the relative effectiveness of various Ter2BX, such as dEap2BX, lEap2BX, 2-dIcr2BX, 4-dIcr2BX, and lCleap2BX along with dIpc2BX for the asymmetric ring opening of three representative meso-epoxides (cyclohexene, cyclopentene, and cis-2,3-butene oxides) is reported. Among all the reagents studied, 2-dIcr2BCl (78–80%) demonstrated significant improvement in enantiomeric excess over

    Nonenzymatic kinetic resolution of racemic secondary alcohols is an efficient synthetic method to obtain optically active compounds in organic chemistry. Catalytic asymmetric acylation of racemic secondary alcohols has been successfully performed with achiral benzoyl chloride in the presence of only 0.3 mol% of chiral diamine (3) derived from (S)-proline, combined with 0.5 equivalent of triethylamine

    The present invention relates to a method of producing vicinal diols from a compound, the method characterised by the step of reacting the compound with a moderately strong acid in the presence one or more reagents capable of supplying hydroxyl groups wherein the moderately strong acid is a strongly reducing agent, but has a conjugate base that is a weak nucleophile. In preferred embodiments the moderately strong acid is hypophosphorous acid and the reagent(s) capable of supplying hydroxyl groups is 2-propanol in water, where 2-propanol is water soluable and organic. This method is particularly applicable to the production of vicinal diols of steroids, including lanosterol. Once vicinal diols of lanosterol diols are formed they are then capable of being further reacted to produce high purity lanosterol.
    本发明涉及一种从化合物中制备邻二醇的方法,其特征在于将该化合物与中等强度酸在一种或多种能够提供羟基的试剂的存在下反应,其中中等强度酸是一种强还原剂,但具有弱亲核副基。在优选实施例中,中等强度酸是亚磷酸,能够提供羟基的试剂是水中的2-异丙醇,其中2-异丙醇是水溶性和有机的。该方法特别适用于类固醇,包括麦角甾醇的邻二醇的生产。一旦形成了麦角甾醇的邻二醇,它们就能够进一步反应,产生高纯度的麦角甾醇。
