Abstract

RuCl3 catalyzes the efficient Ugi-type Groebke–Blackburn condensations of aldehydes and 2-amino pyridines with isocyanides under solvent free conditions without any ligand or activator. It is shown that RuCl3 catalyzed aminoimidazole derivatives can be efficiently prepared under mild conditions and high tolerance with typical yields around 94%.
