Four new 14-crown-4 macrocyclic ligands containing either a pyridine or a 4-pyridone subcyclic unit have been prepared. Two of the 4-pyridono-crowns contained lipophilic hydrocarbon substituents. The starting octyl- and benzyl-substituted 4-oxa-1,7-heptanediols were prepared from the 2-octyl- or 2-benzyl-1,3-propane-diol. When the two substituted 4-oxa-1,7-heptanediols were treated with tosyl chloride
