The one-pot multicomponent synthesis of benzo[g]imidazo[1,2-a]quinolone-6,11-dione derivatives in good to high yields, from readily available starting materials including ethylenediamine, 1,1-bis(methylthio)-2-nitroethene, 2-hydroxy-1,4-naphthoquinone and aromatic aldehydes is described. This protocol has the advantages of simple work-up, mild reaction conditions and provides a powerful entry into
从容易获得的起始原料包括乙二胺,1,1-双(甲硫基)-一锅多组分合成苯并[ g ]咪唑并[1,2 - a ]喹诺酮-6,11-二酮衍生物描述了2-硝基乙烯,2-羟基-1,4-萘醌和芳族醛。该方案的优点是后处理简单,反应条件温和,并为进入与生物活性杂环有关的稠合多环结构提供了有力的途径。
