appealing benefits they offer. Imidazole fused polyheterocycles containing ringjunctionnitrogen have attracted considerable interest in medicinal chemistry in view of their uses as anti-inflammatory [2], anticancer [3], antibacterial [4] and antituberculosis [5] agents. The importance of imidazo[1,2-a]pyridine is evident from the fact that it is prevalent in several marketed drugs such as olprinone
A microwave-promoted highly flexible and efficientUgi-type multicomponent reaction of heterocyclic amidines with aldehydes and isocyanides catalyzed by zirconium(IV) chloride was developed. The general protocol offered the very reliable synthesis of a library of medicinally important, widely versatile N-fused aminoimidazoles in excellent yields. Poorly reactive heterocyclic amidines, functionally

Multiplemulticomponentreactions rapidly assemble complex structures. Despite being very productive, the lack of selectivity and the reduced number of viable transformations restrict their general application in synthesis. Hereby, we describe a rationale for a selective version of these processes based in the preferential generation of intermediates which are less reactive than the initial substrates
