procedure for the preparation of the polysubstituted dihydropyridines was developed through a unique four-component reaction of aromatic aldehydes, malononitrile, arylamines, and acetylenedicarboxylate in ethanol in the presence of triethylamine as a base promoter. This four-component reaction is atom-efficient, high-yielding, and applicable to a wide variety of four-component reactions.
在三乙胺作为碱助催化剂的存在下,通过芳族醛,丙二腈,芳基胺和乙炔二羧酸酯在乙醇中的独特的四组分反应,开发了一种制备多取代的二氢吡啶的实用有效的方法。该四组分反应是原子有效的,高产率的,并且适用于各种各样的四组分反应。
