Some reactions of 6-ketocholestanyl acetate
Enol acetylation of 6-ketocholestanyl acetate by acetic anhydride-sulphuric acid or acetic anhydride-perchloric acid gave the Δ⁵-enol acetate, which on bromination yielded the known 5α-bromo-ketone. Isopropenyl acetate enol acetylation afforded a 1:1 mixture of Δ⁵ - and Δ⁶-isomers, the ratio being d...
