Abstract: The absolute configuration of the title compound, C16H24O, has been deduced from the chemical pathway. The six-membered ring has a roughly half-chair conformation with the quaternary C atom as the flap. The seven-membered ring displays a chair conformation. In the crystal, there is a weak C-H...O hydrogen bond between the methyl­ene group of the cyclo­propane ring and the carbonyl group of a screw-axis-related mol­ecule, which builds up a zigzag-like chain along the b-axis direction.
