title: 6-Meth-oxy-2-phenyl-4,4a,6,7,8,8a-hexa-hydro-2H-pyrano[3,2-d][1,3]dioxine-7,8-diyl bis-(4-methyl-benzene-1-sulfonate).
abstract: In the title α-D-glucopyran-oside derivative, C(28)H(30)O(10)S(2), each heterocyclic ring adopts a chair conformation. In the tri-substituted ring, the meth-oxy and one sulfonate group occupy axial positions, whereas the second sulfonate group occupies an axial position. The phenyl group on the other ring is in an equatorial position. In the crystal, supra-molecular chains propagating along [100] are formed through C-H⋯O and C-H⋯π inter-actions.
