New 15,15-dialkyl-substituted derivatives of the estradiol of general formula I ##STR1## in which R.sup.1 and R.sup.2, independently of one another, are each a hydrogen atom or a straight-chain alkanoyl group with 1 to 10 carbon atoms, a branched-chain alkanoyl group with 3-10 carbon atoms, an alkanoyl group of 3-10 carbon atoms containing a cycloaliphatic structure of 3-6 carbon ring atoms or a benzoyl group, and R.sup.3 and R.sup.4, independently of one another, are each a straight-chain alkyl group with 1 to 10 carbon atoms or a branched-chain alkyl group with 3 to 10 carbon atoms, are described, a process for their production and initial products for this process. The new compounds have--also after oral administration--high estrogenic effectiveness and are suitable for the production of pharmaceutical agents.
本发明涉及一种通式I的新的15,15-二烷基取代雌二醇衍生物,其中R1和R2分别独立地是氢原子或具有1到10个碳原子的直链烷酰基团,具有3-10个碳原子的支链烷酰基团,含有3-6个碳环原子的环烷基结构或苯甲酰基团,而R3和R4分别独立地是具有1到10个碳原子的直链烷基团或具有3到10个碳原子的支链烷基团,描述了它们的制备过程和该过程的初始产物。这些新化合物具有高雌激素效力,即使经口服也有效,并适用于制备药物。
