Tetracyclo[7.3.0.0<SUP>3,7</SUP>.0<SUP>4,10</SUP>]dodecane-2,8-dione ("[8]diisotwistane-2,8-dione") was synthesized from <I>trans</I>-<I>anti</I>-2,5-dioxo-7,8-diethoxycarbonylbicyclo[2.2.2]octane which was prepared by the Diels-Alder reaction of hydroquinone with diethyl fumarate. 8,9-Benzotricyclo[4.3.1.0<SUP>3,7</SUP>]decane ("benzoisotwistane") was also synthesized from 2-oxo-5-<I>endo</I>-ethoxycarbonyl-7,8-benzotricyclo[2.2.2]octane which was obtained by the Diels-Alder reaction of β-naphthol with ethyl acrylate.
