ABSTRACT
In the title mol-ecule, C(30)H(52)O(4), the three six-membered rings are in chair conformations, the cyclo-pentane ring is in an envelope form and the tetra-hydro-furan ring has a conformation inter-mediate between half-chair and sofa. In the crystal, mol-ecules are linked by inter-molecular O-Hâ¯O hydrogen bonds into helical chains along [100]. Two intra-molecular O-Hâ¯O hydrogen bonds are also present. One C atom of the tetrahydrofuran ring and its attached H atoms are equally disordered over two sets of sites.
