Abstract: 2-(1H-benzo[d]imidazol-2-yl)anilines reacted with haloketones including 5-chloropentan-2-one and 6-chlorohexan-2-one catalyzed by iodine, giving benzo[4,5]imidazo[1,2-c]pyrrolo[1,2-a]quinazoline and 6H-benzo[4,5]imidazo[1,2-c]pyrido[1,2-a]quinazoline derivatives, respectively. This domino-type reaction formed two new heterocycles and three new covalent bonds in one-pot procedure and provided a… read more here.
