Sodium borohydride reduction of Reichstein's Substance S (I) furnished 17α, 20β, 21-trihydroxy-4-pregnen-3-one (II) and 4-pregnene-3β, 17α, 20β, 21-tetrol (IV), and the structure of the latter was verified. Selective oxidation by N-bromoacetamide converted compound (IV) into (II) and catalytic hydrogenation of compound (V) was accompanied by hydrogenolysis to afford the triacetate (VI) of Reichstein's Substance K and 20β, 21-diacetoxyallopregnan-17α-ol (VIII), which was led to the free steroid (VII) for identification.
