title: 1,3-Bis[2-hy-droxy-2-(6-meth-oxy-2,2-dimethyl-3a,5,6,6a-tetra-hydro-2H-furo[2,3-d][1,3]dioxol-5-yl)eth-yl]-2,3-dihydro-1H-1,3-benzodiazol-2-one.
abstract: In the title benzimidazolone, C(27)H(38)N(2)O(11), 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 mol-ecular structure, the hy-droxy groups are hydrogen-bond donors to the carbonyl O atom. Weak inter-molecular C-H⋯O hydrogen bonding is present in the crystal structure.
