Reacción de dobles enlaces con NO2Na-AcOH en presencia de F3B I. Derivados del colestano

Abstract

The 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.

Dos de los autores (R.F. y J.A.S.) agradecen al Ministerio de Educación y Ciencia las ayudas recibidas para "Formación de Personal Investigador". Este trabajo ha sido realizado dentro del "Programa de Investigación" suscrito con el Ministerio de Educación y Ciencia.
