Sodium Acetate → HCID 12801522, compound

Participants

Reaction Steps

At 0° C., 2.6 g of 18-methyl-15α-tetrahydropyran-2-yloxy-4-estren-17β-ol in 50 ml of methylene chloride is stirred with 3.6 g of pyridinium chlorochromate and 1.2 g of sodium acetate at 0° C. After 3.5 hours, the mixture is diluted with methylene chloride, washed with water, and dried. Chromatography of the crude product on silica gel with 3-3.5% acetone/hexane yields 1.6 g of 18-methyl-15α-tetrahydropyran-2-yloxy-4-estren-17-one as an oil. [α]D20 =+87.4°.
