2-c]imidazole]-6′-carbonitrile derivatives has been developed by a sequential three component one-pot reaction of isatin, malononitrile and hydantoin or thiohydantoin derivatives catalyzed by Et3N in water, an environmentally friendly reaction medium. This method provides clean and efficient access of privileged spirooxindole derivatives tethered with pyrrolizidine moiety from the readily available starting materials
通过连续的三组分一锅法反应,开发了一种新颖且直接的合成药理学上有前景的螺[吲哚啉-3,7'-吡咯并[1,2- c ]咪唑] -6'-腈衍生物的方法。伊斯丁, 丙二腈 和 乙内酰脲或Et 3 N催化的硫代乙内酰脲衍生物水,一种环境友好的反应介质。该方法提供了从容易获得的起始原料中清洁和有效地获得与吡咯并吡啶部分相连的特权螺氧杂吲哚衍生物的方法。
