Zusammenfassung
In this study, novel SO3H-dendrimer functionalized magnetic nanoparticles (Fe3O4@D-NH- (CH2)(4) SO3H) were prepared and characterized by using FT-IR, X-ray diffraction patterns, scanning electron microscopy, transmission electron microscopy, thermogravimetry analysis, and energy-dispersive X-ray spectroscopy. The synthesized nanosized catalyst was successfully applied to the synthesis of highly substituted pyrans and polyhydroquinolines via a straightforward one-pot multicomponent condensation reaction. The key advantages are the short reaction time, high yields, simple workup, and purification of products by simple recrystallization from ethanol. (C) 2019 Elsevier Ltd. All rights reserved.
