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.
