Abstract
Dextrin nanoparticles are usually applied as biocompatible biopolymers. Natural catalysts such as nanodextrin have high catalytic activity. Dextrin has attracted researchers' attention because of its unique chemical structure, water-solubility, biodegradability, biocompatibility, abundance, affordability, and availability to produce the applied materials. On the other hand, dextrin is a suitable substrate for trifluoride ions and some metal ions due to its hydroxyl groups. Thus, the nano-Fe3O4@dextrin/BF3 catalyst was synthesized with readily available, unique, and efficient capability. The synthesized catalyst was characterized by different techniques such as Energy-Dispersive X-ray (EDX) analysis, Fourier Transforms Infrared (FT-IR) spectroscopy, X-Ray Diffraction (XRD) pattern, Scanning Electron Microscopy (SEM) image, and Thermo Gravimetric Analysis (TGA). Then the effect of adding nano-Fe3O4@dextrin/BF3 to the reaction of aldehydes, ethyl acetoacetate, and urea was studied on the synthesis of 3,4-dihydropyrimidin-2(1H)-ones derivatives under solvent-free conditions using an electrical mortar-heater. The synthesis of 3,4-dihydropyrimidin-2(1H)-one derivatives was carried out at 70 ˚C using a negligible amount (30 mg) of catalyst, in a short time of 20 min with a very suitable yield of 80-92%.
