Abstract:

In the title compound, C24H24O14, the stereochemistry at the cyclobutane ring is cis-anti-cis and the –COOMe groups in the bicyclic rings are syn to each other. The molecule lies on a twofold rotation axis. In the crystal, weak C—H...O hydrogen bonds connect molecules into chains along [001], forming R22(10) rings.
