Aluminum Oxide Nanoparticle as a Valuable Heterogeneous Nanocatalyst in the Synthesis of 2-Aminothiazole Scaffolds

An efficient methodology for the preparation of 2-aminothiazoles is achieved by one-pot reaction of methylcarbonyls, thiourea and iodine in the presence of an aluminum oxide nanoparticle as an active nanocatalyst at 85 °C in DMSO solvent. Al2O3 nanoparticles have been prepared via co-precipitation method and their structures were confirmed using Fourier transform infrared radiation (FT-TR), X-ray diffraction (XRD), scanning electron microscopic (SEM), and energy-dispersive analysis of X-ray (EDAX) analyses. Advantages of this efficient synthetic approach include higher purity and excellent yield of products, easy isolation of products and convenient manipulation.
