The invention relates to new 8a-oestra-1,3,5(10)-triene derivatives having the formula:
in which
R, = H or a free, esterified or etherified hydroxy group; R2 = H or a free, esterified or etherified hydroxy group, with the proviso that at least one of the substituents R1 and R2 is different from H;
R3 alkyl (1-4 C) and
R4 = 0 or (aX) (βY), in which
X = H or aliphatic hydrocarbyl (1-4 C) and
Y = a free, esterified or etherified hydroxy group and the enantiomers and racemic mixtures thereof, and also extends to processes for their preparation and to pharmaceutical compositions containing said new compounds.
