We report the regioselective synthesis of 6-amino-2,3-anthracenedimethanol (2) beginning from commercially available 2,3-dimethylanthraquinone. The more reactive 9- and 10- positions of the anthracene core are masked from electrophilic attack by “protection” of the molecule through formation of its corresponding ethano anthracene (“barrelane”) adduct. Also reported is the synthesis of the corresponding
我们报道了从商业上可获得的2,3-二甲基
蒽醌开始的6-
氨基-2,3-
蒽二
甲醇(2)的区域选择性合成。通过形成相应的
乙醇蒽蒽(“ barrelane”)加合物,对分子进行“保护”,从而使
蒽核反应性更高的9位和10位免受亲电攻击。还报道了由容易获得的
蒽醌-2,3-二
羧酸合成相应的5-
氨基异构体(1)。
