The title compound, C27H33NO5, obtained from diethyl ether, crystallizes in space group P2(1) with four molecules in the asymmetric unit. The dioxinone and imide rings are almost planar, whereas the cyclohexane and cyclohexene rings form distorted conformations. The crystal structure confirms an earlier proposal about the stereoselectivity of Diels - Alder reactions to spirocyclic chiral 1,3- dienes.
