Pregnane derivatives have been obtained from the cyanohydrins of androst-4-en-3, 17-dione and of 3β-acetoxyandrost-5-en-17-one. It has been shown that when both a nitrile group and an ethylenedioxy group are present in an androstane derivative a Grignard reaction in anisole takes place simultaneously at the two groups.
