Diethyl 9,10-dihydro-9,10-ethanoanthracene-11,12-trans-dicarboxylate.
The title compound, C(22)H(22)O(4), is the product of the Diels-Alder reaction of anthracene with fumaric acid diethyl ester. The molecular C(2) symmetry is nearly fulfilled in the crystal. Only the terminal torsion angles about the O-CH(2) groups show significant differences.
