“…Saponification and chromatographic separation produced the crystalline 11ahydroxyprogesterone (Va) with ^PVH 242 µ, log e 4.18, X ^ .13 1660 cm.-1 ( ,ßunsaturated ketone), 1704 cm.-1 (20-ketone), and free hydroxyl band. Acetylation furnished the crystalline acetate (Vb) while chromium trioxide oxidation led to the known (11,12) for the product obtained in the microbiological oxidation of progesterone.…”
