Synthesis of bis-cellobiose and bis-glucose derivatives of azacrown macrocycles as hosts in complexes with acetylsalicylic acid and 4-acetamidophenol
摘要:
Two new C-2 symmetric bis-cellobiose and bis-glucose azacrown derivatives were prepared according to the one-step procedure using azacrown ethers and azidosaccharides. Their complexes with aspirin and paracetamol were studied with the use of proton NMR spectroscopy. It was found that these pseudo-cryptands bind aspirin and paracetamol but each one in a different manner. (C) 2014 Elsevier Ltd. All rights reserved.
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.
