  The present invention is a process for the preparation of 17β-hydroxy-7α-methyl-19-nor-17α-pregn-5(10)-en-20-yn-3-one (17α-ethynyl-17β-hydroxy-7α-methyl-5(10)-estren-3-one, tibolone) of formula 1, which comprises hydrolysis of 17α-ethynyl-17β-hydroxy-7α-methyl-5(10)-estrene 3,3 -cyclic ketals of formula 2, where groups R 1 , R 2 , R 3 and R 4 are hydrogen atoms or alkyl groups, or R 1 and R 3 , taken together with the carbon atoms within the dioxolane ring to which they are attached, form an alicyclic ring fused to the dioxolane ring, with R 2 and R 4 being hydrogen atoms, or R 1 and R 3 together with the carbon atoms to which they are attached form an aromatic ring fused to the dioxolane ring, where R 2 and R 4 , taken together, form a chemical bond within said aromatic ring. In addition, the present invention includes an intermediate, compound of formula 2 and two processes to prepare 17α-ethynyl-17β-hydroxy-7α-methyl-5(10)-estrene 3,3 -cyclic ketals of formula 2: (a) by contacting 17α-ethynyl-17β-hydroxy-7α-methyl-4-estren-3-one with vicinal diols in the presence of a protic acid, and (b) by contacting 7α-methyl-5(10)-estrene-17-one 3,3-cyclic ketals of formula 4, where R 1 -R 4 are defined as above, with metal acetylides, in inert solvents.

  本发明涉及一种制备17β-羟基-7α-甲基-19-去氢-17α-孕-5（10）-烯-20-炔-3-酮（17α-乙炔基-17β-羟基-7α-甲基-5（10）-雌甾-3-酮，替泼酮）的方法，其包括对式2的17α-乙炔基-17β-羟基-7α-甲基-5（10）-雌甾-3,3-环糊精酮进行水解，其中基团R1、R2、R3和R4是氢原子或烷基，或者R1和R3与它们所附着的二氧兰环内的碳原子一起形成螺环并与二氧兰环融合，其中R2和R4是氢原子，或者R1和R3与它们所附着的碳原子一起形成与二氧兰环融合的芳香环，其中R2和R4一起在该芳香环内形成化学键。此外，本发明还包括一个中间体，化合物的式子为2，并且还包括两种制备式2的17α-乙炔基-17β-羟基-7α-甲基-5（10）-雌甾-3,3-环糊精酮的方法：（a）通过在质子酸存在下与邻二醇接触17α-乙炔基-17β-羟基-7α-甲基-4-雌甾-3-酮，和（b）通过在惰性溶剂中与金属乙炔基化合物接触式4的7α-甲基-5（10）-雌甾-17-酮3,3-环糊精酮，其中R1-R4的定义如上。
