A process for forming one or the other of a 17-α-aryl or 17-β-aryl steroidal compound in diastereo excess is disclosed. The process utilizes a 17-keto steroid to form a Δ16-17-aryl-steroid compound or a 17-β-hydroxy-17-α-aryl steroid compound that are reduced or deoxygenated, respectively, in the presence of Raney nickel to form a 17-β-aryl- steroid or 17-α-aryl steroid, respectively, in a diastereo ratio of at least 3:1.
