aromatic aldehydes, substituted chalcones are generated via a 15-min, one-pot synthesis. Diversification of aromatic groups, including electron-withdrawing, electron-donating, and heterocyclic substitutions, has led to the isolation of over twenty colored, solid chalcone products. Furthermore the methodology can be extended to the synthesis of benzylidenemalononitriles as well as methyl and ethyl α-cyano
描述了一种在微波辐射下轻松生产α-氰基查耳酮的新颖方法。利用苯甲酰基乙腈和芳族醛之间的Knoevenagel缩合,通过15分钟的一锅法合成生成取代的查耳酮。芳香族基团的多样化,包括吸电子,供电子和杂环取代,已导致分离出二十多种有色固体查耳酮产品。此外,该方法可以扩展到亚苄基丙二腈以及甲基和乙基α-氰基肉桂酸酯的合成。
