Abstract

Procedure for preparing unsaturated steroid compounds at position 9 (11) and/or 16, which have the partial formula I: **(See formula)** where the pairs of symbols R1-R2 and R3-R4 represent double bonds between adjacent carbon atoms, but one of these pairs R1-R2 and R3-R4 can also represent two hydrogen atoms, or, when R1-R2 represents a double bond, R3 can represent hydrogen and R4 can also represent a hydroxyl group; M represents the remaining part of the steroid skeleton, optionally having substituents and/or other double bonds on rings A and B; and R5 represents a hydrogen atom, or an alkynyl, alkenyl or alcohol group of 1 to 4 carbon atoms, optionally substituted with oxygen, nitrogen or metal atom containing groups; said process characterized in that a steroid compound having hydroxyl groups in position 11 and/or 17 is dehydrated by treatment, in an ether or in a solvent having a dielectric constant greater than 6, with the complex compound formed by reacting thionyl chloride with a tertiary organic base.
