Abstract

A process for the preparation of 3-oxo 8 alpha-H 17 beta-hydroxy 17 alpha-ethynyl estra-5 (10) -en, racemic or optically active forms, characterized in that the ketone function is protected from 3-oxo 8 alpha- H 17 beta-hydroxy estra-5 (10) -one by formation of a ketal, the ketalized product is subjected to the action of an oxidizing agent, the corresponding 17-ketone compound is obtained, which by ethynylation followed by acid hydrolysis, provides the 3-oxo 8 alpha-H 17 beta-hydroxy 17 alpha-ethynyl estra-5 (10) -one desired.
