A simple one-pot synthesis of two derivatives of 1,4-dihydropyridines has been described under reflux conditions using copper iodide nanoparticles (CuI NPs) as a catalyst in high yields. This method demonstrated four-component coupling reactions of aldehydes and ammonium acetate via two pathways. In one route, the reaction was performed using 2 eq ethyl acetoacetate while in the other one 1 eq ethyl
已经描述了在回流条件下使用碘化铜纳米粒子 (CuI NPs) 作为催化剂以高产率简单地一锅合成 1,4-二氢吡啶的两种衍生物。该方法通过两种途径证明了醛和乙酸铵的四组分偶联反应。在一种路线中,使用2当量乙酰乙酸乙酯进行反应,而在另一种路线中使用1当量乙酰乙酸乙酯和1当量丙二腈。CuI NPs 被重复使用和回收,没有任何活性和产品产量损失。值得注意的是,由于药理和生物学活性,1,4-二氢吡啶的广泛范围引起了人们的极大兴趣。
