Abstract
A method for preparing unsaturated derivatives of the pregnane series having the general formula I: ** (See formula) ** wherein R1 represents hydrogen, alpha-methyl or beta-methyl or methylene, R2 and R3, which are identical or different, represent hydrogen or an acyloxy group of 1 to 6 carbon atoms, and a double of 16.17 may be present further bond, characterized in that a substituted 3-acyloxy-Delta3,5-pregnadiene of the partial general formula II is halogen: ** (See formula) ** wherein R4 represents an acyloxy group of 1 to 6 carbon atoms, the formed addition product is hydrolysed, and the 6 beta-halogen-Delta4-3-ketone obtained is dehydrohalogenated.
