The title compound, C34H32O6, was synthesized from the ozonolysis of (2S,3S,9S,10S)-6,13-dimethylene-2,3,9,10-tetraphenyl-1,4,8,11-tetraox acy clotetradecane. Two different conformers of the title compound co-crystallized in a tetragonal unit cell and were structurally analyzed by X-ray crystallography.
