Abstract
The dihedral angles between ring planes of the title compound, C19H26O 4, a D-ring lactone, indicate a slightly curved molecular profile. All ring junctions are trans. A hydrogen bond between the hydroxyl group of ring A and the carbonyl group of ring D links the molecules head-to -tail in helical chains parallel to the 2(1) screw axis along a.
