Tetramethylguanidine-functionalized silica-coated iron oxide magnetic nanoparticles catalyzed one-pot three-component synthesis of furanone derivatives
AbstractTetramethylguanidine-functionalized silica-coated iron oxide magneticnanoparticles as a productive and reusable catalyst have been applied for the one-pot three-component synthesis of furanone derivatives (4a–o). In addition to the characterization of all products by FT-IR, \(^1}\hbox HNMR}\) and \(^13}\hbox CNMR}\) spectroscopy, single-crystal X-ray analysis of ethyl 5-oxo-2-phenyl-4-(phenylamino)-2
