摘要 靛红可与卤代烃发生亲核取代反应生成N-烷基靛红衍生物。以靛红和二溴烷烃为原料,通过探索不同反应条件,找到最佳合成靛红衍生物的方法:以5-氯靛红与不同链长的二溴烷烃以1∶8比例投料,K_2CO_3作为碱,DMF为溶剂,在室温反应36 h,产物收率较高,其收率在70%~83%之间。该方法具有操作简单,危险性小,反应条件温和,和高效等优点。 Isatin can react with halogenoalkane to produce N-bromoalkyl Isatin derivatives. After screening the reaction conditions,an optimal method for the synthesis of N-bromoalkyl Isatin derivatives was discovered. 5-chloro-Isatin reacted with different chains of dibromoalkanes with a ratio of 1 ∶8 in DMF for 36 h at room temperature,using potassium carbonate as a base. The yield of the product was between 70% and 83%. This synthetic method has many advantages of convenient operation,lower danger,mild reaction conditions and high yield.
