    摘要:
    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氟化试剂反应来进行亲电性氟化,例如与分子氟或三氟甲基次氟酸盐反应,在抑制自由氟自由基形成的条件下,例如通过存在自由基抑制剂如氧气或硝基苯,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氟三氯甲烷或氯仿/氟三氯甲烷中,从而使得该氢原子被氟原子亲电性取代。氟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氟化的方向。该文还公开了新型14α-氟类固醇,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。

  • Chemical process for fluorinating a tertiary carbon atom in the steroid

    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 fluorination 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.
