Abstract: The two oxazolidine rings (A and B) of the title compound, C34H44N2O4, display roughly half-chair conformations, which could be described as twisted on the C-O bond. Together, the fused oxazolidine rings have a butterfly shape, with the H atoms attached to the ring junction C atoms in a cis orientation. The cyclohexane rings of both p-menthone fragments display chair conformations. The absolute configuration could not be determined from the X-ray diffraction data, but the relative configuration of the stereocentres could be deduced.
