(4R)- and (4'S)-Spiro(oxirane-2,4'-5alpha-cholestan-3'beta-ol) (1) and (2) were made from (4'R)- and (4'S)-spiro(oxirane-2,4'-5alpha-cholestan-3-one) (8) and (9). Alkaline hydrogen peroxide oxidation of 4-methylene-5alpha-cholestan-3-one (7) gave compounds (8) and (9) as a readily separable (1:1) mixture. Reduction of (9) to (2) provided access to a compound which could not be made by other methods.
