Two new series of macrocyclic polyether-diester ligands (4-15) containing a pyridine subcyclic unit have been prepared by treating various oligoethylene glycols and sulfur-containing oligo-ethylene glycols with 2,6- and 3,5-pyridine dicarbonyl chlorides. The compounds prepared from 2,6-pyridine dicarbonyl chloride were: 3,6,9,12-tetraoxa-18-azabicyclo[12.3.1 ]oetadeca-1(18), 14,16-triene-2,13-dione (4); 3,6,9,12,15-pentaoxa-21-azabieyclo[15.3.1]heneicosa-1(21),17,19-triene-2,16-dione (5); 3,6,12,15-tetraoxa-9-thia-21-azabicyclo[15.3.1 ]heneicosa-1(21),17,19-tri-ene-2,16-dione(6); 3,9,15-trioxa-6,12-dithia-21-azabicyclo[15.3.1]heneicosa-1(21),17,19-triene-2,16-dione (7); 3,6,9,12,15,18-hexaoxa-24-azabicyclo[18.3.1 ]tetracosa-1(24),20,22-triene-2,19-dione (8); 3,6,9,12,15,18,21-heptaoxa-27-azabicyclo[21.3.1]heptacosa-1(27),23,25-triene-2,22-dione (9); and the corresponding analogues from 3,5-pyridine dicarbonyl chloride (10-15). The solid potassium thiocyanate complex of compound 5 was also prepared.
