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

A facile and eco-friendly synthesis of imidazo[1,2-a]pyridines using nano-sized LaMnO3 perovskite-type oxide as an efficient catalyst under solvent-free conditions
and reusable catalyst showed excellent catalytic activity for the synthesis of imidazo[1,2-a]pyridines. LaMnO3 catalyst could be recovered and reused in five reaction cycles, giving a total TON = 2790 and TOF = 372. The products were prepared under solvent-free conditions without any additives. Principal features of this simple method include non-hazardous reaction conditions, low catalyst loading and
