The relative configuration of the title compound, C(11)H(18)O(3), which was synthesized using a catalytic asymmetric Gosteli-Claisen rearrangement, a diastereoselective reduction with K-Selectride and an Evans aldol addition, was corroborated by single-crystal X-ray diffraction analysis. The five-membered ring has an envelope conformation with a dihedral angle of 29.46 (16)° between the coplanar part and the flap (the hydr-oxy-bearing ring C atom). In the crystal, mol-ecules are connected via bifurcated O-H⋯(O,O) hydrogen bonds, generating [010] chains.
