Diisopropyl 3-[(E)-2-(3,4-dimethoxy­phen­yl)ethen­yl]-5-oxocyclo­hex-3-ene-1,1-dicarboxyl­ate


The title compound, C(24)H(30)O(7), displays a trans configuration with respect to the C=C bond. The cyclo-hexenone 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 cyclo-hexenone ring and the benzene ring is 7.85 (9)°. The meta and para meth-oxy O atoms are displaced by 0.003 (7) and 0.031 (4) Å, respectively, from the benzene ring to which they are attached.
