The first tandem double palladium-catalyzed aminations: synthesis of dipyrido[1,2-a:3',2'-d]imidazole and its benzo- and aza-analogues

A new strategy for the synthesis of the title compounds via a regio- and chemoselective one-pot inter- and intramolecular Buchwald-Hartwig amination of 2-chloro-3-iodopyridine with aminoazines and -diazines is reported.
