secondary amines. The reaction of 6e,h with benzotriazolylacetone yielded 14a,b. Also, the reaction of 6a,b,d-f,h with glycine and hippuric acid in acetic anhydride afforded pyridazinone derivatives 17a-f. Synthesis of pyridazine carboxylic acid derivatives 22a,b from the reaction of 6b,e with dimethyl acetylenedicarboxylate (DMAD) in the presence of triphenylphosphine at room temperature is also reported
甲基酮 1a-g 与二甲基甲酰胺二甲基缩醛 (DMFDMA) 的反应得到烯胺酮 2a-g,其与重氮化的芳香胺 3a、b 偶联得到相应的芳基腙6a-h。化合物6a-h与一些芳族杂环胺的缩合得到亚氨基芳基腙9a-m。Enaminoazo 化合物 12a,b 可以从 6c 与仲胺缩合获得。6e,h与苯并三唑基丙酮的反应产生14a,b。此外,6a,b,df,h 与甘氨酸和马尿酸在乙酸酐中的反应得到哒嗪酮衍生物 17a-f。还报道了在室温下在三苯基膦存在下,由 6b,e 与乙炔二羧酸二甲酯 (DMAD) 反应合成哒嗪羧酸衍生物 22a,b。
