Abstract:
:A new, efficient, and solvent-free cyclocondensation reaction of arylmethylidenepyruvic acids with 6- aminouracils is presented that uses a catalytic amount of ZnO nanoparticles (ZnO Nps) as a recyclable catalyst at 70 °C. This protocol has the advantages of high yields (91-98%), easy work-up, very short reaction time (2 h), and using environmentally friendly procedure.
