Abstract

The invention comprises steroids of the general formula <FORM:0923737/IV(a)/1> wherein R represents an ethynyl or ethyl radical, and the preparation thereof by reacting 3a -acetoxy-5b -androsta-11,17-dione with an alkali metal acetylide to form a steroid of the above formula wherein R represents an ethynyl radical, and, when required catalytically hydrogenating the product to form the corresponding steroid wherein R represents an ethyl radical.
