Piperidine-4-carboxylic acid (PPCA) functionalized Fe3O4 nanoparticles (Fe3O4-PPCA) were prepared by the one pot co-precipitation of iron oxide in the presence of PPCA. Grafting of chlorosulfonic acid on the synthesized Fe3O4-PPCA nanoparticles afforded sulfamic acid-functionalized magnetic nanoparticles (Fe3O4-SA-PPCA). The catalytic activity of Fe3O4-SA-PPCA as a novel catalyst was probed through one-pot synthesis of 2,3-dihydroquinazolin-4(1H)-ones and polyhydroquinolines derivatives. The heterogeneous catalyst could be recovered easily and reused many times without significant loss of its catalytic activity.
