AbstractThe reaction of cholesterol with NaNO2/BF3 in AcOH yields its 5α-acetyl-6-nitrimine derivative, which is easily transformed into cholestan-3β,5α-diol-6-one 5-acetate. A similar treatment of cholest-4-ene gives the acetates of cholestan-5α-ol-4-one, cholestan-5β-ol-4-one and of the corresponding 4-nitrimine derivatives. This represents a new method for obtaining α-acetyl- and α,β-unsaturated ketones.
