Abstract
A process for the preparation of steroids of the general formula i: ** (see formula) ** (wherein: x represents hydrogen or an acyl group of 1 to 6 carbon atoms, y represents hydrogen, or an alkyl group of 1 to 4 carbon atoms, a vinyl group, an allyl group or an ethynyl group, z represents hydrogen or a methyl group, v represents an acyl group of 1 to 6 carbon atoms) by adding a compound of the general formula ii thereto: ** (see formula) ** Having a hydroxy group on ring a in allyl position (where x, y and z have the same meanings as those defined above) in that: a) a compound of general formula ii is acylated with an anhydride of an acid having from 1 to 6 carbon atoms, in the presence of an iodine and tertiary base catalyst, or b) a compound of the general formula iii: ** (see formula) ** Wherein x, y and z have the same meanings as those defined above) is reduced to a compound of general formula ii; the excess reducing agent is decomposed; the compound of the general formula ii is reacted directly in the solvent mixture with an anhydride of an acid having from 1 to 6 carbon atoms, in the presence of an iodine and tertiary base catalyst, and the compound of the general formula i.
