Abstract
The title compound, C24H30O7, displays a trans configuration with respect to the C=C bond. The cyclohexenone ring has an envelope conformation; the flap atom (with the isopropoxycarbonyl groups) is displaced by 0.664 (3) Å from the plane of the other five ring atoms and the carbonyl O atom. The dihedral angle between the cyclohexenone ring and the benzene ring is 7.85 (9)°. The meta and para methoxy O atoms are displaced by 0.003 (7) and 0.031 (4) Å, respectively, from the benzene ring to which they are attached.
