Reaction of 2-acetylbenzoimidazole 1 with some arylaldehydes under different conditions gave chalcones, 1,5-pentanediones and pyridines. Treatment of chalcones with various types of reagents gave the corresponding new pyridines, thienopyridines, pyndo[2,3:4′,5′]thieno[3′, 2′-d]-pyrimidin-8-ones via initial addition of active methylene or amino group to the double bond followed by cyclization.
