A green heterogeneous nanocatalyst, Cu(II)-PBABMD complex immobilized on core-shell magnetic γ-Fe 2 O 3 @HAp, was successfully designed, synthesized, and characterized by FTIR, XRD, FESEM, EDX, VSM, TGA, BET, ICP-OES, and TEM techniques. The magnetic Cu(II) nanocatalyst was employed as a novel, ecofriendly, recyclable, and safe catalyst for the one-pot, threecomponent condensation of 6-amino-2-thioxo-2,3-dihydropyrimidin-4(1H)one, 3-(1-methyl-1H-pyrrol-2-yl)-3-oxopropanenitrile and aromatic aldehydes to produce new pyrido [2,3-d]pyrimidine derivatives, in refluxing EtOH with excellent yield (90-97%) and short reaction time (8-13 min). The nanocatalyst was used and recycled in eight runs without significant leaching or loss of its catalytic activity.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
