ABSTRACT
A simple and one-pot synthesis of naphthopyranopyrimidines is reported by the three-component condensation reaction of aldehydes, β-naphthol, and 1,3-dimethylbarbituric acid using ZnAl2O4 nanoparticles under microwave irradiation. This flexible and nano-catalytic procedure showed good recyclability and provides a clean condensation reaction in a short reaction time.
