derivatives are simply prepared via a three-component reaction in the presence of taurine as the catalyst. All these reactions are performed in water, a green solvent. The advantages of using of taurine as the catalyst are it is environmentally friendly, low cost, commercially available, easy to separate from the reaction mixture, and has high reusability. Use of this catalyst results in acceptable reaction
牛磺酸(2-氨基乙烷磺酸)是存在于人体和许多其他生物中的半必需氨基酸,被用作绿色生物有机催化剂,以促进醛与丙二腈之间的Knoevenagel反应。同样,四酮也可以通过Knoevenagel反应生成,然后进行迈克尔加成反应。2-氨基-3-氰基-4 H-吡喃衍生物可通过以下方法简单地制备牛磺酸作为催化剂的三组分反应。所有这些反应均在绿色溶剂水中进行。使用牛磺酸作为催化剂的优点是环境友好,成本低廉,可商购,易于从反应混合物中分离并且具有高可重复使用性。使用这种催化剂可在不使用任何有机溶剂的情况下获得可接受的反应时间,高产率和高纯度的所得产物。
