Abstract
3,4-Dimethoxyphenol with a trans p -nitrostyryl group at the side chain was electrolyzed in acetic anhydride containing n Bu 4 NBF 4 to afford a tricyclo[5.3.1.0 1,5 ]undec-9-ene-8,11-dione, while the cis isomer was converted into a tricyclo[5.4.0.0 1,5 ]undec-9-ene-8,11-dione as a major product. In the case of several phenols with an α,β-unsaturated ketone or ester grouping, the corresponding tricyclo[5.4.0.0 1,5 ]undec-9-ene-8,11-diones were also obtained in good yields.
