Stability of the Complexes of Bis-Saccharide Crown Ethers withp-Toluenesulfonamide

Abstract

Two new C2 symmetric macrocycles, soluble in water, were prepared according to the one‐step procedure using azacrown ethers and azidosaccharides. Their complexes with p‐toluenesulfonamide were studied by proton NMR spectroscopy. The influence of the size of azacrown ether and the solvent effect on the stability of the guest–host complexes were examined.
