The one pot, three component reaction of p-hydroxy benzaldehyde, β-ketoester, and ammonium acetate afforded the corresponding monopodal 1,4-dihydropyridines as building blocks, which in turn converted into diversified novel bipodal, tripodal, and tetrapodal 1,4-dihydropyridines with different alkylating agents through conventional as well as microwave assisted reactions. The unambiguous structural
对羟基苯甲醛、β-酮酯和乙酸铵的一锅三组分反应得到相应的单足1,4-二氢吡啶作为构建单元,进而转化为多样化的新型双足、三足和四足1,4-二氢吡啶与不同的烷化剂通过常规以及微波辅助反应。在 2D NMR(HH COZY 和 CH COSY)的帮助下,绘制了所有合成化合物的明确结构限制。
