报道了一种在高温水中,以醛、3-芳基-3-氧丙腈、2-乙酰吡啶和乙酸铵为原料,微波辅助多组分反应合成新的2,2'-联吡啶衍生物的高效方法。此外,芳香族醛与1,2-二苯乙烷发生反应。产生结构复杂的五芳基吡啶。这种化学反应为构建面向多样性的聚芳吡啶骨架提供了一种高效而有前景的合成策略。
An efficient reagent-controlled approach for the regiospecific synthesis of new 2,2'-bipyridine derivatives in high-temperature water via microwave-assisted multicomponent reactions of aldehydes, 3-aryl-3-oxopropanenitrile, 2-acetylpyridine, and ammonium acetate is reported. Furthermore, aromatic aldehydes reacted with 1,2-diphenylethanone. resulting in Structurally complex penta-arylpyridines. This chemistry provides an efficient and promising synthetic strategy to diversity-oriented construct poly arylpyridine skeleton.
