Synthesis of bis-cellobiose and bis-glucose derivatives of azacrown macrocycles as hosts in complexes with acetylsalicylic acid and 4-acetamidophenol

• Tandem Staudinger/aza-Wittig reaction of a 1-azidosaccharide derivatives with azacrown ethers.
• Complexing properties received macrocycles towards to acetylsalicylic acid and 4-acetamidophenol.
• Stoichiometry of complexes indicated by the Job’s plot using 1H NMR spectroscopy.

Two new C2 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 pseudocryptands bind aspirin and paracetamol but each one in a different manner.
