Abstract: The title compound, C₂₁H₂₀O₇, also known as purpuriol, was isolated for the first time from natural product sources. The cyclohexene ring adopts a half-chair conformation with an axially attached methyl benzoate and equatorially attached benzoyloxy substituents. The methyl benzoate and benzoyloxy groups are essentially planar. The dihedral angle between these groups is 9.2  (2)°. O-HO intermolecular hydrogen bonds link the molecules into chains along the a axis and the chains are interlinked by C-HO hydrogen bonds and C-H interactions.
