SynopsisThe crystal structure of the title compound, a model for the glycosyl linkage between the asparagine side chain and N-acetyl glucosamine in glycoproteins, has been determined and compared to other model structures. The pyranose ring in the crystal is in the 4C1 chair conformation and the amide functions at C1 and at Cz are both oriented such that the amide protons are nearly trans to their respective sugar-ring protons. Coupling constants determined from the fully assigned proton nmr spectrum in aqueous solution are consistent with the conformation in the crystal.
