Özet
In the molecule of title compound, C15H20O6, also known as cynarinin A, the cyclopentane ring having twist conformation and a γ-lactone ring assuming an envelope conformation are trans- and cis-fused, respectively, to a cycloheptane ring adopting a twist-chair conformation. In the crystal, O—H⋯O hydrogen bonds link neighbouring molecules, forming a three-dimensional network. Theoretical calculations of the molecular structure using the CNDO approximation and MOPAC PM3 geometry optimization are in satisfactory agreement with the results of the X-ray structure analysis.
