The title compound, C17H22O8, is an example of a product obtained from a cyclodicarbonylation reaction using diacetylenic substrates.The five-membered ring assumes a near-envelope conformation with the two acetate chains lying practically in the plane of the four coplanar ring atoms, C1, C2, C4 and C5, while the ethoxycarbonyl groups (attatched to the atom forming the 'flap') are oriented in opposite directions.The conjugated C=C-C=O chromophore systems are planar and are not parallel.Intramolecular interactions are in the range 2.43(3)-2.60(4) Angstroem.
