Chemoselective substitution reactions of 2-bromo-3-methoxy-1,4-naphthoquinone were studied here. In the reactions of 2-bromo-3-methoxy-1,4-naphthoquinone with a variety of alkylamines, 2-alkylamino-3-bromo-1,4-naphthoquinones resulted in high yields. Alkylthiols, on the other hand, were found to form 2-alkylthio-3-methoxy-1,4-naphthoquinones in their reactions with 2-bromo-3-methoxy-1,4-naphthoquinone in the presence of an amine.
本文研究了 2-溴-3-甲氧基-1,4-萘醌的化学选择性取代反应。在 2-溴-3-甲氧基-1,4-萘醌与多种烷基胺的反应中,2-烷基氨基-3-溴-1,4-萘醌的产率很高。另一方面,烷基硫醇在胺的存在下与 2-溴-3-甲氧基-1,4-萘醌反应生成 2-烷硫基-3-甲氧基-1,4-萘醌。
