Abstract

1,208,039. 1 - Hydroxy - 7α - methyl - estradiol derivatives. SCHERING A.G. 12 June, 1968, No. 27939/68. Heading C2U. Novel steriods of the formula (in which R 1 and R 2 is each H, C 1-6 alkyl or a saturated oxyheterocyclic group or an acyl radical; and R 3 is H or an optionally halogensubstituted C 1-6 aliphatic hydrocarbon group) and the novel 1,3 - diacetate and 1,3 - bis - tetrahydropyranyl ether of 1 - hydroxy - 7α - methyl - estrone are prepared by etherification or esterification of 1- hydroxy - 7α - methyl - estrone and formation of the group α - R 3 (#- OR 2 ) from the free, esterified or etherified 17 - ketone by known methods. In the products free hydroxy groups can be esterified or etherified and/or esterified or etherified hydroxy groups hydrolysed. 1 - Hydroxy - 7α - methyl estrone is prepared by reacting 7α -methyl - estrone (prepared by hydrolysis of the tetrahydropyranyl ether) with lead tetra-acetate in glacial acetic acid to give 7α - methyl - #<SP>1,4</SP> - estradien - 10# - ol - 3,17 - dione acetate and treating this with a little conc. H 2 SO 4 in acetic anhydride. The steriods of the above general formula have oestrogenic activity and inhibit ovulation, and they may be made up into pharmaceutical compositions for oral or parenteral administration.
