Abstract
Novel 16a (C1- 4 alkyl) - 3,20 - diketo - D 4,6-pregnadienes are prepared by oxidation of the corresponding D 4-compounds with a quinone having an oxidation-reduction potential of less than - 0.5 v. The novel steroids are stated to have progestative, pregnancy-maintaining and gonadinhibiting properties, and they may be made up into pharmaceutical compositions for oral or parenteral administration with suitable carriers.
