Application of palladium-catalyzed amination to the synthesis of polyazamacrocycles containing 3,5-disubstituted pyridine
The synthesis of a new family of nitrogen- and oxygen-containing macrocycles, which employs palladium-catalyzed amination of 3,5-dihalopyridines, is described. Synthetic approaches to cyclodimers have been elaborated via bis(pyridyl)substituted polyamines and bis(polyamino) substituted pyridines.
