Abstract

In this paper we report regioselective tandem metal-catalyzed aminations on dihaloquinolines (2-chloro-3-iodoquinoline and 2, 3-dibromoquinoline) with amino (benzo)(di) azines. Eight new heterocyclic scaffolds of the dipyridoimidazole type could be synthesized. By controlling the reaction temperature selective C-2 intermolecular Pd- catalyzed amination on 2, 3-dibromoquinoline with amino (benzo)(di) azines can be ...
