Abstract

In the title compound (kokosanolide B), C(30)H(48)O(3), the hexa-hydro- and octa-hydro-naphthalen-2-one ring systems are connected through an ethyl-ene fragment, with a C-CH(2)-CH(2)-C torsion angle of 176.2 (2)°. The cyclo-hexene ring adopts a half-chair conformation, while the other six-membered rings adopt distorted chair conformations. In the crystal, adjacent mol-ecules are linked into a zigzag chain along the b axis by O-H⋯O hydrogen bonds involving the hy-droxy and carbonyl groups.
