In this work, we successfully employed electrochemical conditions to promote a Hofer–Moest, intramolecular Friedel–Crafts alkylation sequence. The reaction proceeds under mild conditions, employing carboxylic acids as starting materials. Notably, the electrochemical process performed in batch was adapted to a continuous flow electrolysis apparatus to provide a significant improvement. This catalyst-free
在这项工作中,我们成功地利用电化学条件促进 Hofer-Moest 分子内 Friedel-Crafts 烷基化序列。该反应在温和条件下进行,使用羧酸作为起始原料。值得注意的是,分批进行的电化学过程适用于连续流动电解装置,以提供显着的改进。这种无催化剂的电化学方法可生产一系列可用于 API 合成的四氢萘。
