Ugi-Smiles couplings of 4-substituted pyridine derivatives: A fast access to chloroquine analogues

Abstract : 4-Hydroxy and mercapto pyridines were successfully tested in Ugi-Smiles couplings. Such multicomponent reactions applied to quinoline derivatives afford a very convenient and short synthesis of antimalarial analogues. © 2011 American Chemical Society.
