Description
Summary: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.
