Abstract: In the title compound, C₂₄H₂₇NO₁₀S₂, derived from L-sorbofuranose, the fused five-membered rings display envelope conformations. The two tosylate branches are in equatorial positions with respect to the furanose ring, while the hydroxy group is in the axial position. In the crystal structure, the hydroxy group is involved in intermolecular O-HO hydrogen bonds, linking molecules in chains along [100].
