Abstract
The title compound, C23H34O6, a ring D lactone, has two acetoxy groups in p ositions 3 alpha and 4 beta. All ring junctions are trans which results in a planar molecule. The two acetoxy groups have different behaviour, one of them being disordered and exhibiting double-bond delocalization. The ordere d acetoxy group is involved in two weak intramolecular C-H ... O bonds.
