Some phenols with an olefinic side chain have been electrolyzed under various conditions to afford tricyclo[5.3.1.01,5]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.
一些具有烯烃侧链的苯酚已经在各种条件下进行了电解,得到了三环[5.3.1.0 1,5 ] undec-9-en-8,11-二酮。这些产物用甲醇中的碳酸钾处理,得到相应的反式氢氢唑烷,其被认为是生物活性倍半萜和二萜类化合物的有前途的合成中间体。
