A one-pot three-component condensation of aromatic aldehyde, aromatic ketone, and malononitrile leading to an efficient synthesis of 2-amino-4,6-diarylbenzene-1,3-dicarbonitrile and 1,2-dihydro-2-oxo-4,6-diarylpyridine-3-carbonitrile has been carried out in a mortar just by grinding or heating under solvent-free conditions. Compared with the classical reaction conditions, these new synthetic methods have the advantages of excellent yields, shorter reaction time, and mild reaction conditions.
一种一锅三组分冷凝反应方法,使用芳香醛、芳香酮和丙二腈,在研钵中通过简单的研磨或无溶剂条件下加热,实现了2-氨基-4,6-二芳基苯-1,3-二腈和1,2-二氢-2-氧-4,6-二芳基吡啶-3-腈的高效合成。与传统反应条件相比,这些新的合成方法具有优良的产率、更短的反应时间和温和的反应条件等优点。
