afforded Diels-Alder adduct 14 and fragmentation product 32 with 2 and 3 respectively whereby reaction occurred on the less substituted double bond. No adducts were isolated upon treatment of naphthoquinone-sulfide 22 with either 2 or 3. The Diels-Alder adducts of benzoquinone-sulfoxide 9 and naphth

The 2,5-bisacrylate-substituted 1,4-benzoquinone bisketal 7a was synthesized by electrochemical oxidation of the corresponding dimethoxybenzene 6. The methyl ester 7a was transesterified to the corresponding ethyl, n-propyl and isopropyl esters 7bΟͺ7d by Ti(OEt) 4 catalysis and to the corresponding n
