A catalytic methodology is reported that enables the efficient, operationally simple and environmentally friendly synthesis of diverse 1,4-dihydropyridines and 3,4-dihydropyrimidin-2(1H)-ones, including some relevant drugs and pharmacologically active derivatives. This strategy is based on the use of a 3D printed Al2O3 woodpile material that was sintered to generate a rigid structure with controlled
报道了一种催化方法,该方法能够有效,操作简单且环保地合成各种1,4-二氢吡啶和3,4-二氢嘧啶-2(1 H)-one,包括一些相关药物和药理活性衍生物。该策略基于使用3D打印的Al 2 O 3木桩材料,该材料经过烧结以产生具有受控孔隙率和显着催化性能的刚性结构。3D打印的Al 2 O 3催化剂在Biginelli和Hantzsch反应中显示出路易斯酸的显着功效,并且可以回收并重复使用十次而不会降低活性。卓越的E 因素,出色的可回收性和可扩展性,广泛的底物范围,短的反应时间,优异的产率,无溶剂条件和易于分离的程序是该方法的关键特征。
