Cholesteryl acetate (1) on oxidation with NBS in DMSO furnishes six different compounds which have been identified as 5α-bromo-6-keto-cholestan-3β-yl acetate (2), 6α-bromo-5β-hydroxycoprostan-3β-yl acetate (3), 5α-hydroxy-6-keto-cholestan-3β-yl acetate (4), 5α,6β-dihydroxycholestan-3β-yl acetate (5), 3β,5α-dihydroxycholestan-6-one (6) and cholestane-3β,5α,6β-triol (7) by chemical studies and spectral (IR, mass, PMR, 13C NMR) data.Compound 3 is perhaps reported for the first time.
