作为一种有趣的可持续性软纳米材料,石墨碳氮化物因其独特的电子结构和化学稳定性而受到了广泛的学科关注。在极性和强酸性磺化磁性石墨氮化碳(Fe 3 O 4 @gC 3 N 4 -SO 3)存在下的一系列多取代吡啶的超声辅助制备H)在较温和较快的反应条件下在水中作为绿色介质的报道。芳族醛与无环和环状酮,丙二腈和乙酸铵的一锅顺序多组分反应以良好或优异的产率得到了吡啶衍生物。考虑到生态友好和经济考虑,该方法提供了以环境友好的方式产生生物活性吡啶衍生物的直接且方便的途径。Fe 3 O 4 @gC 3 N 4 -SO 3 H在几个反应组上显示出高稳定性和可重复使用性,而没有明显的活性损失,因此,该方法是一种廉价且环保的方法。
N2-Methyl- or aryl-substituted 2-amino-4-aryl-5,6,7,8-tetrahydroquinoline-3-carbonitriles were synthesized via a four-component, one-pot reaction of aromatic aldehyde, cyclohexanone, malononitrile, and amines in basic ionic liquid [bmim]OH with good to excellent yields. During this transformation, at least 11 bonds were cleaved and 7 new bonds were constructed.

multicomponent reaction of aromatic aldehydes with acyclic and cyclic ketones, malononitrile and ammonium acetate was afforded the pyridine derivatives in good-to-excellent yields. In view of eco-friendly and economic considerations, this approach offers a straightforward and convenient route to generate biologically active pyridine derivative in an environmentally friendly manner.
