Some phenols with an olefinic side chain have been electrolyzed under various conditions to afford tricyclo[,5]undec-9-en-8,11-diones. These products were treated with potassium carbonate in methanol to give rise to the corresponding trans-hydroazulenes which are regarded as a promising synthetic intermediate of bioactive sesqui- and diterpenoids.
