An environmentally friendly and efficient synthesis of a series of 1,4-dihydropyridines was developed by the practical one-pot reactions of aldehydes with ammonium acetate and 1,3-dicarbonyl compounds such as alkyl acetoacetate, 5,5-dimethyl-1,3-cyclohexanedione, 1,3-cyclohexanedione, and 2,4-pentanedione in water without any additives under refluxing conditions.
通过醛类与乙酸铵以及1,3-二羰基化合物(如乙基乙酰乙酸酯、5,5-二甲基-1,3-环己二酮、1,3-环己二酮和2,4-戊二酮)在水中的实际一步反应,无需任何添加剂并在回流条件下,开发了一系列1,4-二氢吡啶的环境友好且高效的合成方法。
