Synthesis and characterization of fluconazole-functionalized magnetic nanoparticles as a catalyst for the synthesis of 3-aryl and 3-amino-imidazo[1,2-a]pyridines
Fluconazole immobilised on modified Fe3O4–SiO2 core–shell nanoparticles was synthesised, characterised and used as a catalyst in synthesis of 3-aryl and 3-amino-imidazo[1,2-a]pyridines.
Imidazoazines have been synthesized by a one-potthree-component condensation reaction of an aldehyde, a 2-aminoazine and an isocyanide in the presence of the cellulose sulfuric acid, as an effective bio-supported catalyst in excellent yields. The reaction work-up is simple and the catalyst can be easily separated from the product and reused in several times.
