An Efficient Synthesis of Tri- and Tetrasubstituted Imidazoles from Benzils Using Functionalized Chitosan as Biodegradable Solid Acid Catalyst

An environmentally benign, highly efficient one-pot four-component synthesis of highly functionalized imidazole derivatives using different aldehydes, substituted amines, benzil, and ammonium acetate in the presence of biodegradable and highly efficient catalyst chitosan–SO3H were described. Chitosa...
