respectively. Compounds 3a, 3b react with hydrazine and phenyl hydrazine to afford the azine‐bis derivatives 5a, 5b and 7a, 7b, whereas 16a, 16b react with the same reagents to afford the pyrazolyl amine derivatives 17a, 17b and 18a, 18b, respectively. Compounds 3a, 3b react also with dimethylformamide dimethylacetal to afford the enaminonitriles 8a, 8b, whereas 16a, 16b react with the same reagent
将二甲苯胺1a,1b与氰基乙酸乙酯2和乙酸乙酯基苯甲酰15缩合,分别得到氰基乙酰苯胺3a,3b和β-二酮16a,16b。化合物3a,3b与肼和苯肼反应可得到嗪双衍生物5a,5b和7a,7b,而16a,16b与相同的试剂反应可得到吡唑基胺衍生物17a,17b和18a,18b分别。化合物3a,3b也与二甲基甲酰胺二甲基乙缩醛反应,得到烯胺腈8a,8b,而16a,16b与相同的试剂反应,仅得到烯胺酮19b。烯腈8a,8b与肼和苯基肼反应,分别分别得到嗪双衍生物11a,11b和14a,14b。
