BiFeO3 Magnetic Nanoparticles: A Novel, Efficient and Reusable Magnetic Catalyst for the Synthesis of Polyhydroquinoline Derivatives

Herein, it has been shown that the bismuth ferrite magnetic nanoparticles (BFO-MNPs) are new, efficient and recyclable catalysts for the synthesis of polyhydroquinoline derivatives by the Hantzsch reaction. The one-pot four-component cyclocondensation reaction of dimedone, aromatic aldehydes, ethyl acetoacetate and ammonium acetate was carried out under solvent-free conditions. The...
