Hydrocyanicacid adds to the 16-double bond of Δ5,16-pregnadien-3β-ol-20-one acetate to produce 16α-cyano-Δ5-pregnen-3β-ol-20-one. Similar additions of hydrocyanicacid to Δ16-20-oxo pregnenes are described. By alkaline hydrolysis of the 16α-nitrile group the corresponding acid was obtained, of which several derivatives are described.
