Abstract
A compound of the formula ##STR1## wherein R.sub.1 is an aliphatic hydrocarbon of 1 to 8 carbon atoms, R.sub.2 and R.sub.3 are individually hydrogen or alkyl of 1 to 4 carbon atoms, G is a hydrocarbon of 1 to 18 carbon atoms optionally containing at least one heteroatom and linked to the steroid nucleus by a carbon atom, X is X.sub.A or X.sub.B, X.sub.A is selected from the group consisting of hydrogen, alkyl of 1 to 8 carbon atoms, aralkyl of 7 to 15 carbon atoms, acyl of an organic carboxylic acid of 1 to 8 carbon atoms and Y is -B-O--CO--A-Z, B is a saturated or unsaturated, linear or branched alkylene of 1 to 8 carbon atoms, A is a saturated or unsaturated, linear or branched alkylene of 1 to 6 carbon atoms and optionally interrupted or ended by a bivalent aromatic or is a bivalent aromatic and Z is --COOH or --SO.sub.3 H which may be salified with an alkali metal, alkaline earth metal, an organic amine or --NH.sub.4 or X.sub.B is --COAZ, A and Z are defined as above and Y is selected from the group consisting of --C.tbd.C--R.sub.4, --CH.dbd.CH--R.sub.4 and --CH.sub.2 --CH.sub.2 --R.sub.4, R.sub.4 is selected from the group consisting of hydrogen, halogen, alkyl of 1 to 6 carbon atoms, trialkylsilyl having 3 to 12 carbon atoms and phenyl, the alkyl and phenyl being optionally substituted and the 13-wavy line indicates that R.sub.1 can be in the .alpha.- or .beta.-position having antiprogestomimetic and antiglucocorticoid properties among others.
