Resumen:
In this paper we report the use of an intramolecular Ugi reaction to synthesize new 4-azacholestanes diversely subtituted both at N-4 and C-5. Both the scope and the stereochemical outcome of this approach were studied by varying the nature of the components necessary for this multicomponent reaction.  In sight of our results we concluded that this methodology can be applied to obtain 4-azasteroids targeted to find new biologically active compounds.
