The synthesis of macrocycles containing two pyridine and twopolyamine fragments was carried out by the Pd-catalyzedamination of 2,6-dihalopyridines using polyamines and dioxadiamine. Two alternative approaches were elaborated and compared: via intermediate formation of Nα,Nω-bis(6-halopyridin-2-yl)polyamines or via 2,6-bis(polyamino)substituted pyridines. The yields of linear and cyclic products
