   Der durch die vorliegende Erfindung erreichte Fortschritt besteht darin, dass wertvolle Diketone erhalten werden, die selbst eine höhere physiologische Wirksamkeit aufweisen, wie die als Ausgangsmaterial benutzten Oxyketone und die in Substanzen höherer physiologischer Wirksamkeit übergeführt werden können.

 are dissolved in 450 cm3 of glacial acetic acid. About 1 g of chromic acid is added to this solution and the mixture is kept at room temperature for one day. The solvent is then evaporated and the androstandion- (3. 17) from the solution, which has been concentrated until crystallization begins, by adding water

   The progress achieved by the present invention is that valuable diketones are obtained which themselves have a higher physiological activity, such as the oxyketones used as starting material and which can be converted into substances of higher physiological activity.
