Abstract
Procedure for the preparation of estratriene of general formula: ** (See formula) ** wherein the dotted lines at positions 6-7 and 9-11 indicate the optional presence of another link; K represents a hydrogen atom, an aliphatic hydrocarbon group with less than 10 carbon atoms, a cycloalkyl group with less than 7 carbon atoms, an aryl group with less than 11 carbon atoms and which may be substituted by a nitro group or by methoxy groups, an adamantyl group, a furyl group or a thienyl group; R1 represents a hydrogen atom or an OR2 group, in which R2 represents a hydrogen atom, an aliphatic hydrocarbon group with less than 4 carbon atoms, a beta-dimethyluminoethyl group, an acyl residue derived from acetic acid or sulfuric acid or an alkali metal salt thereof, or a 1H-tetrazoyl group; and R3 represents a hydrogen atom, a hydroxyl group, an acetoxy group, or an oxo group, characterized in that it comprises decarboxylating an estratriene-17 β -carboxylic acid of general formula: ** (See formula) ** wherein R and R2 are defined as above and optionally convert, a estratriene of general formula: ** (See formula) ** thus obtained in another compound of general formula I.
