An efficient approach to the synthesis of 1,2,5-trisubstituted imidazole derivatives was investigated via a DABCO-promoted formal [3+2]-annulation reaction of substituted N-arylbenzimidamides and substituted β-nitrostyrenes. The annulation reaction is implemented easily to afford the corresponding products in moderate to good yields with excellent regioselectivity.
