Abstract :
An efficient and one-step versatile method for the synthesis of benzimidazoles and 1H-imidazo[4,5-b]pyridines from quinoxalinones and their aza-analogues have been developed on the basis of the novel ring contractions of 3-aroyl-quinoxalinones and their aza-analogues with 1,2-arylenediamines.
