以儿茶酚为起始原料, 与二氯甲烷在碱性条件下进行亲核取代, 再进行氯甲基化反应、亲核取代、水解、脱羧, 酰胺化得化合物2~6, 后经霍夫曼重排得3,4-亚甲二氧基苯乙胺(8), 最后缩合、环化得盐酸黄连素1, 合成盐酸黄连素的总收率为13.6 %. 化合物1~9的结构经过1H NMR、13C NMR、质谱确认.

关键词: 儿茶酚, 3,4-亚甲二氧基苯乙胺, 盐酸黄连素, 合成

Berberine chloride was synthesized starting from pyrocatechol in overall 13.6% yield. The key steps include a Hofmann rearrangement, chloromethylation, nucleophilic substitution, hydrolysis, decarboxylation, and cyclization. All of intermediates were determined by 1H NMR, 13C NMR, MS techniques.

Key words: pyrocatechol, 3,4-methylenedioxyphenylethylamine, berberine chloride, synthesis
