A highly efficient procedure for the one-pot synthesis of polysubstituted pyrrole derivatives by the reaction between of aniline derivatives, beta-diketones or beta-ketoesters, and beta-nitrostyrene derivatives in the presence of Fe3O4@SiO2-CPTMS-guanidine-SO3H as a reusable magnetic nanocatalyst is reported. The magnetic nanocatalyst was prepared and fully characterized by FTIR spectroscopy, scanning electron microscopy, energy dispersive X-ray spectroscopy, X-ray diffraction analysis, thermogravimetric analysis, and vibrating sample magnetometry.

A novel and simple three-component system has been developed to synthesize substituted pyrroles from corresponding amines and nitrostyrenes using (diacetoxyiodo)benzene at reflux temperature in ethanol. The good to excellent yields were obtained with different types of functional groups. (C) 2013 Elsevier Ltd. All rights reserved.
