A novel and facile synthesis of 2-arylbenzothiazole derivatives was accomplished in good yields via the novel reductive cyclization of bis-(2-benzalaminophenyl)disulfide promoted by the TiCl4/Sm system. The advantages of this new method are the easily accessible starting materials, short reaction time, and moderate to good yields.
通过由 TiCl4/Sm 系统促进的双-(2-苯甲氨基苯基)二硫化物的新型还原环化,以良好的收率完成了 2-芳基苯并噻唑衍生物的新型且简便的合成。这种新方法的优点是原料容易获得,反应时间短,收率中等至良好。
