Abstract
Abstract Multiheteromacrocycles are disclosed that contain as part of the macrocycle, assemblies of 2,6-dimetylylpyridine (and their corresponding amine oxides), 2,5-dimethylylfuran, 2,5-dimethylyltetrahydrofuran, Diels-Alder adducts of 2,5-dimethylylfuran (and their reduction products), 2- and 4-substituted 1,3-dimethylylbenzenes, pentamethylene, or p-phenylene coupled through oxygen to one another or to ethylene, o-phenylene, or 1,1-binaphthyl-2,2- units (always coupled through oxygens) to form multidentate ligands for complexing selectively alkylammonium or metal cations.
