| titleOfInvention | 2-oxo-3-oxo-estra 4,9-dienes having hormonal - activity |
| abstract | 2-Oxo-3-oxo-estra 4, 9-dienes having hormonal activity Title steroids, of general formula (I): where R1=H, acyl or alkyl, R2=H, or an opt. substd. hydrocarbon radical, are prepd by reacting a hydrogenation agent, preferably H in the presence of a catalyst such as palladium on alumina, inactivated by the addition of lead acetate, pyridine or both, with the corresponding 2-oxo-3-oxo estra 4,9,11-triene (II) to produce the novel 2-oxo-3-oxo estra 5(10) 9 (11) -diene (III). This is isomerised with for example a strong acid such as perchloric or polyphosphoric, giving the title 4,9-dienes (I) which have known hormonal activity, as do their triene intermediates. Example prepares 2-oxo-3-oxo 17 beta-benzoyloxy estra 4,9-diene. |
