Abstract: In the title compound, C₂₉H₄₄O₅, the ester substituent in ring A is equatorial. The six-membered rings A and C have chair conformations and ring B has a half-chair conformation. The B/C and C/D ring junctions are trans, whereas the tetrahydrofuran ring E is cis-fused to the cyclopentane ring D. An intermolecular O-HO hydrogen bond is observed.
