The title compound, C(15)H(20)O(3), crystallizes with two independent mol-ecules in the asymmetric unit. In both mol-ecules, the seven-membered ring adopts a chair conformation. In the crystal structure, inter-molecular O-H⋯O hydrogen bonds link the mol-ecules into chains extending in the  direction. The absolute configuration was assigned on the basis of the starting materials.
