Participants

Reaction Steps

To a suspension of 0.88 g of pyridinium dicromate in 2.2 ml of dichloromethane a solution of 0.50 g of 3β,14β-dihydroxy-5β-androstane-17β-carboxaldehyde (Boutagy J. and Thomas R., Aust. J. Chem., 1971, 24, 2723) in 2.5 ml of dichloromethane was added at room temperature. After 20 hrs the mixture was diluted with diethyl ether and filtered through celite; the filtrate was evaporated to dryness under reduced pressure. The crude product was purified by flash-chromatography (SiO2) using n-hexane/ethyl acetate 6/4 as eluant; the fractions containing the title compound were collected and evaporated to give 0.30 g of the title compound (II-e) as a white foam.
