Abstract

In this work, an efficient and simple synthetic method for preparation of 2, 4, 5-trisubstituted imidazoles has been designed by three-components cyclocondensation of benzil, a variety of aldehydes and ammonium acetate in the presence of L-PYRROLIDINE-2-CARBOXYLIC ACID-4-HYDROGEN SULFATE supported on silica gel as a catalyst under solvent free condition. Moreover, this catalyst has been used for the one-pot, four-component synthesis of 1, 2, 4, 5-tetrasubstituted imidazoles. These synthetic procedures are very simple and affording good to excellent yields of imidazoles derivatives. The key advantages of this process are the elimination of organic solvents, use of nonmetallic, and environmentally benign catalyst and puriﬁcation of products by non-chromatographic method.
