Abstract
The title compound, C30H50O3, which was isolated from a marine endophytic fungus, is a new friedelan derivative. The molecule contains five six-membered rings, which exhibit boat (ring A), distorted boat (ring B) and chair (rings C–E) conformations. The crystal structure is stabilized by intermolecular O—H⋯O hydrogen bonds, which link neighbouring molecules into 12-membered rings.
