    Notes: The new synthesis of 9α-hydroxy-4-androsten-3,17-dione from hydrocortisone is described. The six-step reaction sequence involved degradation of the side chain, dehydration, ketals formation, reduction of the α-epoxide to 9α-hydroxyderivative and ketal groups cleavage. The overall yield is about 12%. Physico-chemical data of two new compounds were determined.
