A simple, efficient and green approach for the synthesis of spiro-dihydropyridines derivatives by one-pot multi-component reaction of isatin or acenaphthoquinone derivatives (1 equiv) with malononitrile (1 equiv) and N,N′-substituted-2-nitroethene-1,1-diamines (1 equiv) in PEG-400 under catalyst-free conditions is described. This method provides several advantages such as environmental friendliness
一种简单,有效且绿色的方法,是通过一锅多组分的靛红或萘醌衍生物(1当量)与丙二腈(1当量)和N,N合成螺二氢吡啶衍生物描述了在无催化剂条件下在PEG-400中的'-取代的-2-硝基乙烯-1,1-二胺(1当量)。该方法具有许多优点,例如环境友好,反应时间短和生物重要化合物合成的简单后处理程序。在体外和计算机上研究了合成的化合物抑制乙酰基和丁酰胆碱酯酶的能力。所有化合物均显示出对乙酰和丁酰胆碱酯酶的中等至高水平活性。体外和计算机模拟研究之间具有良好的相关性。
