Methyl 2-Aza-2-deoxy-4,6-di-O-methyl-2-N-(p-nitrophenylamino)-β-D-erythro-hexopyranosid-3-ulose

All asymmetric C atoms of the title compound, C₁₄H₁₉N₃O₇, are in the R configuration. The azapyranose ring adopts a half-chair conformation with substituents in equatorial and quasi-equatorial positions. The molecular packing is fixed by hydrogen bonds involving the amino group and one of the methoxy substituents.
