Peracetic Acid → HCID 13340606, compound

Participants

Reaction Steps

A solution of 15 g of 3β-acetoxy-5 -cholestane (I) in 250 cc of ethyl acetate was treated with 30 cc peracetic acid (40%) in acetic acid and was irradiated with ultra-violet light of at about 300 mμ wavelength for 24 hours. The resulting reaction mixture was washed consecutively with an aqueous solution of sodium bisulfite, sodium bicarbonate and water and the solvents were evaporated in vacuo to dryness. The residue was chromatographed on a column of silica gel to give 3.5 g of the known 3β-acetoxy-25-hydroxy-5α-cholestane (III), m.p. 125°-126°C and 1.8 g of the known 3β-acetoxy-5α-hydroxy-cholestane (II), m.p. 180°-181°C.
