Sažetak
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, pyrido[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.
