Nanocatalytic one-pot, four-component synthesis of some new triheterocyclic compounds consisting of pyrazole, pyran, and pyrimidinone rings

Abstract

A new series of triheterocyclic compounds containing pyrazole, pyran, and pyrimidinone rings was synthesized<italic>via</italic>a one-pot condensation of ethylacetoacetate, hydrazine hydrate, barbituric acid, and aromatic aldehydes in the presence of catalytic amounts of titanium dioxide nanowires.
