Electrolysis of 2-methoxy-1-cyclopentene-1-carboxylic acids 2 and 12a gave α,β- or β,γ-ring opening products 4, 5a, 7a, and 15. Electrolysis of 2 without separation of anode and cathode compartments gave 6a in a notable yield. 6a is expected to be formed by the reduction of a key intermediate 8, which can be rationalized by leading to 4 and 5. The results from the anodic oxidation of 12 suggest that the C=C double bond function of 12 was initially oxidized giving 14 followed by discharge of the carboxylate anion to afford 15. A possible mechanism for the anodic reaction of 2 and 12 has been discussed.
2-甲氧基-1-环戊烯-1-羧酸2和12a的电解得到α,β-或β,γ-开环产物4、5a、7a和15。在不分离阳极和阴极室的情况下电解2得到6a 的产率显着。 6a 预计是通过关键中间体 8 的还原形成的,可以通过生成 4 和 5 来合理化。12 的阳极氧化结果表明 12 的 C=C 双键功能最初被氧化,得到 14然后释放羧酸根阴离子得到 15。已经讨论了 2 和 12 阳极反应的可能机制。
