  • The reaction of lead tetraacetate with 3.BETA.-hydroxy steroids.
    作者:RIKIO OHUCHI、KENYU SHIBATA、NOBUAKI YAMAKOSHI、HIROMU MORI
    DOI:10.1248/cpb.29.43
    日期:——
    It was found that the reaction of lead tetraacetate with 3β-hydroxy steroids of the 5α-series gave the corresponding 3β, 19-oxido steroids. Only poor yields were obtained in the cases of 3β-hydroxy steroids having no substituent at C-5 (5α-H). Substitution at the 5α-position by an electronegative group such as halogen or acetoxyl enhanced the yield of the 3β, 19-oxido compound. The best result was obtained when a steroid was heated with lead tetraacetate in benzene in the presence of calcium carbonate and a trace of benzoyl peroxide.
    发现四乙酸铅与5α系列3β-羟基甾体化合物的反应产生了相应的3β, 19-氧代甾体化合物。在没有C-5(5α-H)取代基的3β-羟基甾体化合物的情况下,仅得到了较低的产率。通过在5α位引入电负性基团如卤素或乙酰氧基能提高3β, 19-氧代化合物的产率。当甾体化合物碳酸和微量过氧化苯甲酰存在下,与四乙酸铅在苯中加热时,得到了最佳结果。

    Saturated organic compounds containing a hydrogen atom bound to a tertiary carbon atom may be electrophilically fluorinated by reaction with an electrophilic fluorinating agent such as molecular fluorine or trifluoromethyl hypofluorite under conditions whereby the formation of free fluorine radicals is suppressed, e.g. by the presence of a free radical inhibitor such as oxygen or nitrobenzene, the reactants being substantially homogeneously dispersed in a liquid medium, e.g. a solvent medium such as fluorotrichloromethane or chloroform/fluorotrichloromethane, so that the said hydrogen atom is electrophilically replaced by a fluorine atom. The fluoroination is highly selective and, in the case of complex substrates such as saturated steroids which contain a number of tertiary C--H bonds, may be substantially completely confined to replacement of the hydrogen atom at the tertiary carbon atom which has the highest electron density about the C--H bond. The electron density and thus the direction of the fluorination may be controlled by appropriate selection of substituent groupings in the substrate molecule. Novel 14.alpha.-fluorosteroids are also disclosed, including compounds having valuable androgenic or progestational activity and useful synthetic intermediates.
    含有氢原子与三级碳原子相结合的饱和有机化合物可以通过与亲电性化试剂反应来进行亲电性化,例如与分子或三甲基次氟酸盐反应,在抑制自由自由基形成的条件下,例如通过存在自由基抑制剂氧气硝基苯,使得反应物在液体介质中基本均匀分散,例如在溶剂介质中如氯甲烷氯仿/氯甲烷中,从而使得该氢原子被原子亲电性取代。化反应具有高度选择性,在饱和类固醇等复杂底物的情况下,可以基本完全限制在替换具有最高电子密度的三级碳原子上的氢原子。通过适当选择底物分子中的取代基团,可以控制电子密度和因此化的方向。该文还公开了新型14α-固醇,包括具有有价值的雄激素或孕激素活性以及有用的合成中间体的化合物。
