Abstract

The invention comprises 3-keto-4-dehydro-, 3 - keto - 4,6 - bisdehydro-, 3 - keto - 1,4,6 - trisdehydro-, 3 - acyloxy - 3,5 - bisdehydro- and 3-acyloxy-2,4,6-trisdehydro-derivatives of compounds of formula <FORM:1078426/C2/1> and 3-keto-5-dehydro-derivatives of compounds of formula <FORM:1078426/C2/2> wherein -OR1 is a free, esterified or etherified hydroxy group, R2 is a hydrogen atom or a C1- 5 alkyl group, and R is a C1- 5 alkyl group or an aralkyl group, and their preparation by (a) reaction of a 3-keto-D 4-steroid with a cyclic secondary amine to form a 3-enamino-D 3,5-steroid and treating this with an alkylating or aralkylating agent, followed by hydrolysis, (b) reaction of a 3-keto-D 4-steroid with formaldehyde and a thiol to form a 4-thiomethyl ether and subjecting this to reductive desulphurization, or (c) reaction of a 3-keto-D 4-steroid with an alkylating or aralkylating agent in the presence of a proton acceptor, using excess reagent if a 4,4-disubstituted product is desired, followed, if desired, by (d) reduction of a 17-keto-compound to a 17b -hydroxy compound, with partial reoxidation of any 3,17-diol formed, (e) enol acylation or enol ester hydrolysis, or (f) 17-etherification or esterification or ether or ester hydrolysis. The compounds of the invention have anabolic and differential antigonadotrophic activity and may be used in pharmaceutical compositions in combination with a carrier, for example in forms suitable for oral, parenteral or rectal administration.
