Synthesis of pyrido[2′,1′:2,3]imidazo[4,5- b ]quinoline and pyrido[1′,2′:1,2]imidazo[4,5- b ]quinoline and their benzo and aza analogs via tandem catalysis
摘要：
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 achieved.
