Synthesis of 4-azasteroids by an intramolecular Ugi reaction

In this paper we report the use of an intramolecular Ugi reaction to synthesize new 4-azacholestanes diversely substituted 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 reacti...
