一种新型的苯并吡喃并[2,3- b ]吡啶的轻质,一锅,假四组分催化剂和无溶剂合成方法是通过将各种萘酚加成到水杨醛与丙二腈的Knoevenagel缩合得到的亚氨基香豆素衍生物中来实现的,可能会受到另一分子丙二腈的攻击而获得标题产物。该方法的优点是反应条件温和,产物收率高,通用性强,反应时间短和操作简便。

facile, one-pot, pseudofour-component catalyst- and solvent-free synthesis of novel benzopyrano[2,3-b]pyridines is achieved by Michael addition of various naphthols to iminocoumarin derivatives obtained from Knoevenagel condensation of salicylaldehydes with malononitrile, which can be attacked by another molecule of malononitrile to afford the title products. The advantages of this procedure are mild
