Erbstatin dimethyl ether (12) was synthesized by Friedel-Crafts reaction of chloro(methyl- or phenyl-thio)acetonitrile (5a or 5b) with hydroquinone dimethyl ether, followed by reduction to the amine, formylation, and oxidative desulfenylation. By using a similar sequence of reactions, N-acetyl-1, 2-didehydrodopamine dimethyl ether (13) was prepared from veratrole and 5a, b.
Erbstatin 二甲醚(12)是通过氯(甲基或苯硫)乙腈(5a或5b)与二甲醇醌的 Friedel-Crafts 反应合成的,然后经过还原为胺、甲酰化和氧化去硫反应。通过使用类似的反应序列,N-乙酰-1,2-去氢多巴胺二甲醚(13)是由香豆素和5a、b合成的。
