L-Proline as an efficient catalyst for the synthesis of 2,4,5-triaryl-1H-imidazoles

Abstract

L-Proline has been found to be an efficient organocatalyst for one-pot synthesis of 2,4,5-triaryl substituted imidazole by the reaction of an aldehyde, a benzil and an ammonium acetate. The short reaction time and excellent yields making this protocol practical and economically attractive.
