Abstract A new efficient method of synthesizing 3-cyano-pyridine-2(1H)-ones containing variable substituents at position 4 and various aromatic substituents at position 1 of the pyridinone ring has been developed. The method is based on the reaction of ylidenecyanoacetic acid ethyl esters with dimethylformamide dimethyl acetal, the re-amination of obtained derivatives with several aromatic amines in
摘要 开发了一种合成3-氰基-吡啶-2(1H)-酮的新方法,该化合物在吡啶酮环的4位具有可变取代基,在1位具有多种芳香取代基。该方法基于亚叉基氰基乙酸乙酯与二甲基甲酰胺二甲基乙缩醛的反应,所得衍生物在冰乙酸中与几种芳香胺再胺化,中间产物最终环化为目标 N-芳基-3-氰基-吡啶-2(1H)-酮。已经研究了一些合成化合物与几种醛的缩合反应。
