A process for preparing a heterocyclic steroid compound characterized by structure (I) or (II) ** (See formula) ** wherein R and R 'are alkyl groups, Q is a methylene or ethylenic group, Y is a carbonyl, hydroxymethylene or alkylhydroxymethylene group and substituents on the tertiary carbon atoms of ring C are in the trans-anti-trans configuration, in addition to that in the structure (II) the ring A contains an ethylenic bond that ends in the position 5, procedure in which a compound of the structure (III) ** (See formula) ** where R, R ', Y and Q have the meaning set forth above, ring C is saturated or contains an ethylenic bond terminating at position 9, the cyclic bond C: D is in the trans configuration, every hydrogen atom in the position 8 is in an anti position to the hydrogen atom H of the 14-position and every hydrogen atom in the 9-position is in trans position with respect to the hydrogen atom of the 8-position, it is reduced with the addition of a hydrogen atom. hydrogen in each of the carbon atoms of positions 1 and 4 and saturation of all ethylenic bond in the C ring; and, when required, the product is oxidized to convert Q of a hydroxymethylene group to a carbonyl group and the oxidation product, when required, is alkylated to convert Q to an alkylhydroxymethylene group; and, when required, the resulting structure compound (I) is hydrolyzed and, if necessary, isomerized to a compound of structure (II).
