13-Bis2-hy­droxy-2-(6-meth­oxy-22-dimethyl-3a566a-tetra­hydro-2H-furo23-d13dioxol-5-yl)eth­yl-23-dihydro-1H-13-benzodiazol-2-one

摘要

In the title benzimidazolone, C27H38N2O11, which has N-bound glycosidic units, all five-membered O-heterocyclic rings adopt envelope conformations [for the outer rings, the C atom with the dimethyl groups represents the flap atom]. The two glycosidic units are related by a non-crystallographic twofold rotation axis that passes through the carbonyl portion. In the mol­ecular structure, the hy­droxy groups are hydrogen-bond donors to the carbonyl O atom. Weak inter­molecular C—H⋯O hydrogen bonding is present in the crystal structure.
