analysis, we have proved that the recently published results for ethyl 6-amino-5-cyano-4-aryl-1,4-dihydropyridine-3-carboxylate synthesis is in fact an environmentally friendly synthesis of 6-amino-5-cyano-4-aryl-4H-pyran derivatives using a multicomponent room-temperature grinding procedure of ethyl acetoacetate, [(2-aryl)methylene]malononitriles, and ammonium acetate. GRAPHICAL ABSTRACT
摘要 基于 X 射线衍射分析,我们证明最近发表的 6-amino-5-cyano-4-aryl-1,4-dihydropyridine-3-carboxylate 合成结果实际上是 6-amino-5-cyano-4-aryl-1,4-dihydropyridine-3-carboxylate 的环保合成。 -氨基-5-氰基-4-芳基-4H-吡喃衍生物,使用乙酰乙酸乙酯、[(2-芳基)亚甲基]丙二腈和乙酸铵的多组分室温研磨程序。图形概要
