Abstract
Tetracyclo[7.3.0.03,7.04,10]dodecane-2,8-dione (“[8]diisotwistane-2,8-dione”) was synthesized from trans-anti-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[4.3.1.03,7]decane (“benzoisotwistane”) was also synthesized from 2-oxo-5-endo-ethoxycarbonyl-7,8-benzotricyclo[2.2.2]octane which was obtained by the Diels-Alder reaction of β-naphthol with ethyl acrylate.
