Abstract: The structure of the title compound, C₁₇H₂₀O₁₁, has been determined by single-crystal X-ray diffraction at 100 K. The glucopyranose ring exhibits a chair conformation, with all non-H-atom substituents in equatorial positions, and the triple bond is sterically easily accessible, allowing for followup cycloaddition reactions.
