Abstract: The molecule of the title compound, C₁₈H₃₀O₄, can be described as a trans-fused bicyclic system. The carbonyl group lies on the same side as the methoxycarbonyl group, while the OH group is on the opposite side. The six-membered ring has a twist formed conformation, presumably due to the presence of the methyl group next to a bulky methoxycarbonyl group. There are two local pseudo-twofold axes, one passing through two C atoms, the other through the mid-points of two C-C bonds.
