Abstract
The eight new diamide - diester macrocycles 8-15 possessing pyridine / thioether / ether as ligating units have been prepared by dehydrochlo rination of appropriate diacid dichlorides and diols (4 - 7) obtained by aminolysis of diethyl pyridine-2,6-dicarboxylate / diethyl thiodigl ycolate with aminoalcohols. Amongst these macrocycles, the substituted ones elaborate mixtures of three dimensional cisoid ! transoid config urations and the unsubstituted ones are planar. Macrocycles 9, 10. 11, 13 have high order of binding preference for Ag+ and its highest extr action and transport selectivities are shown by 13 and 10, respectivel y.
