Abstract: The crystal structure of the title compound, C₁₆H₂₂N₂O₃, was undertaken in the course of a study on an acylated pseudoephedrine-derived 1,3,4-oxadiazinan-2-one. The conformation adopted by this heterocycle is a contorted half-chair, in which the imide carbonyls are arranged with the carbonyl groups oriented approximately syn to each other. The torsion angle between the imide carbonyl groups is 37.6  (2)°.
