Abstract

In the title compound, C30H52O5, the three six-membered rings are in chair conformations, the five-membered ring is in an envelope form and the tetrahydrofuran ring has a conformation intermediate between half-chair and sofa. Intramolecular O—H...O hydrogen bonds may influence the conformation of the molecule. In the crystal, molecules are linked by intermolecular O—H...O hydrogen bonds, forming a three-dimensional network.
