A novel one-pot three-component reaction of 6-amino-uracil, isatin, and acetophenone was accomplished through a programmed pH variation for the synthesis of 5-(2-oxoindolin-3-yl)-1H-pyrrolo[2,3-d]pyrimidine-2,4(3H,7H)-dione derivatives. The reaction was conducted in a sequential tandem manner to give the oxindole substituted pyrrolo[2,3-d]pyrimidine products in good to excellent yields. Despite of
通过程序设定的pH值变化,可以合成5-(2-氧代吲哚-3-基)-1 H-吡咯并完成6-氨基尿嘧啶,靛红和乙酰苯的新型一锅三组分反应[2, 3 - d ]嘧啶-2,4(3 H,7 H)-二酮衍生物。以顺序串联方式进行反应,以良好至极好的收率得到羟吲哚取代的吡咯并[2,3- d ]嘧啶产物。尽管有时间安排,但所有过程都在一个锅中进行。这些新型化合物中的大多数在体外均显示出窄至良好的抗菌活性谱。
