Abstract: The asymmetric unit of the title compound, C₁₈H₃₀O₄, contains two formula molecules, which are described as trans-fused bicyclic systems. The carbonyl group lies on the same side as the carbethoxy function, while the OH group is on the opposite side. The six-membered rings have chair conformations and the conformations of the 12-membered rings are similar in the two molecules.
