drost-5-en-3beta-ol (5) and 17beta-(3-pyridyl)-16,17alpha-epoxy-5alpha-androst-3beta-ol (6) were synthesized. 3beta-Acetoxyetienic acid was converted in three steps into 5 viaphotolysis of the thiohydroxamic ester 8. Oxidation of an appropriate 16,17-unsaturated precursor (21) with CrO3-pyridine afforded the acetate (23) of 6. Inhibition of the enzyme by 1, the similarly potent 5,6-reduced analogue
