Abstract:
Wherein R is alkyl of 1 to 3 carbon atoms, R.sub.1 is selected from the group consisting of =0, ketals and R.sub.2 is selected from the group consisting of hydrogen and acyl of an organic carboxylic acid of 1 to 12 carbon atoms and X is selected from the group consisting of hydrogen and hydroxy which are valuable intermediates for the preparation of steroids such as adrenosterone.
