Abstract
A new biopolymer-based magnetic nanocomposite was prepared and characterized by Fourier transform infrared (FT-IR) spectroscopy, energy-dispersive X-ray (EDX) analysis, scanning electron microscopy (SEM) and transmission electron microscopy (TEM) images, inductively-coupled plasma atomic emission spectroscopy (ICP-AES) analysis, thermogravimetric/differential thermal (TG/DT) analysis and atomic force microscopy (AFM) image analysis. Then, it was applied as an efficient heterogeneous catalyst in two important three- and four-component one-pot organic condensation reactions for the synthesis of Hantzsch 1,4-dihydropyridine and polyhydroquinoline derivatives in high yields under solvent-free condition at room temperature. The first design and development of a low-leaching bionanostructure, easy separation and reusability of the nanocatalyst, simple work-up procedure, mild, green and environmentally friendly conditions are some important features and advantages of the present work.
