%X 3&#945;-Acetoxy-5&#946;-pregnan-20&#946;-ol (4a) has been converted into the iodo alcohol (6) with lead tetraacetate and iodine. The derived iodo ketone (7) gave good yields of 3&#945;-acetoxy-17,18-cyclo-5&#946;- pregnan-20-one(8a) when treated immediately with potassium t-butoxide and t-butyl alcohol.
