Abstract: The crystal structure of the title compound, C₁₇H₂₄O₉, was determined to confirm its identity. The pyran ring adopts the ⁷C₄ chair form in which all substituents adopt equatorial orientations, except for the one bearing the allyl group, which is axial. The conformation about the bond connecting the allyl group to the ring places the internal alkene C atom gauche to the ring O atom.
