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
