)-2,5-Dioxoperhydrocycloocta[b]furan-3-carboxylic acidAbstract: The anti stereochemistry between the fused rings of the bicyclic lactone ()-2,5-dioxoperhydrocycloocta[b]furan-3-carboxylic acid, C11H14O5, has been established. Intermolecular hydrogen bonds are observed between the carboxylic acid group and the carbonyl O atom of an adjacent molecule.
