Abstract: In the title compound, C₂₁H₃₀O₃, the five-membered ring adopts an envelope conformation, the cyclohexene ring displays a half-chair conformation and the two cyclohexane rings have normal chair conformations. In the crystal structure, weak intermolecular C-HO hydrogen bonding links the molecules into supramolecular chains running along [100].
