In the title compound, which is of interest with respect to stereochemistry and the anomeric effect, two acetyl substituents adopt equatorial orientations and two are axial. The extended structure displays C—H⋯O hydrogen bonding.
The structure of the title compound, C13H18O9, has monoclinic (P21) symmetry. It is of interest with respect to stereochemistry and the anomeric effect. Two acetyl subsituents adopt equatorial orientations and two are axial. The extended structure displays C—H⋯O hydrogen bonding.
