The efficient base-catalyzed synthesis of 3-substituted 2-aminonaphtho[2,3-b]furan-4,9-dione derivatives from readily available precursors such as 2-hydroxy-1,4-naphthoquinone and nitroalkenes under aqueous conditions is described. Interesting features of this methodology are the conversion of a nitro functionality into an amino functionality in the absence of a reducing agent and the development of
描述了在水性条件下从容易获得的前体(例如 2-羟基-1,4-萘醌和硝基烯烃)有效碱催化合成 3-取代 2-氨基萘[2,3-b]呋喃-4,9-二酮衍生物. 这种方法的有趣特征是在没有还原剂的情况下将硝基官能团转化为氨基官能团,并开发了一种三组分反应,用于从醛、2-羟基-1,4-萘醌和硝基甲烷。
