condensation reaction. These S1–S6 compounds were then used in the preparation of 4,5-dihydropyrazol-1-yl derivatives S7–S15. Finally, four new compounds S16–S19 were synthesized from compound (S7, S8, S9, and S12) and 2,4-dinitrophenylhydrazine. Therefore, three known and ten new heterocyclic compounds were synthesized and completely characterized using 1H NMR, 13C NMR, IR, and elemental analysis. GRAPHICAL
摘要 本研究首先以多种苯乙酮衍生物(苯乙酮、对甲基苯乙酮和对甲氧基苯乙酮)和芳香醛衍生物(苯甲醛、对甲基苯甲醛和对苯二甲甲氧基苯甲醛)通过克莱森-施密特缩合反应。然后将这些 S1-S6 化合物用于制备 4,5-二氢吡唑-1-基衍生物 S7-S15。最后,由化合物(S7、S8、S9 和 S12)和 2,4-二硝基苯肼合成了四种新化合物 S16–S19。因此,合成了三种已知的和十种新的杂环化合物,并使用 1H NMR、13C NMR、IR 和元素分析对其进行了完整表征。图形概要
