Abstract Various substituted 3‐phenylindole 2‐carboxylates (1a–c) were prepared according to the literature methods. These carboxylates (1a–c) on reaction with thiosemicarbazide yielded 5‐substituted‐3‐phenylindol‐2‐(1,2,4‐triazole‐3‐thione) (2a–c) on refluxing in pyridine for 8 h. The 5‐substituted‐3‐phenylindole‐2‐[1,2,4‐triazolo‐3‐thioacetic acid] (3a–c) were prepared from 5‐substituted‐3‐phenyl indole‐2‐[1
摘要 根据文献方法制备了各种取代的 3-苯基吲哚 2-羧酸酯 (1a-c)。这些羧酸盐 (1a-c) 与氨基硫脲反应,在吡啶中回流 8 小时后生成 5-取代的-3-苯基吲哚-2-(1,2,4-三唑-3-硫酮) (2a-c)。5-取代-3-苯基吲哚-2-[1,2,4-三唑并-3-硫代乙酸] (3a-c) 由 5-取代-3-苯基吲哚-2-[1,2,4 -三唑-3-硫酮] (2a-c) 与适当的烷化剂和乙酸钠在乙酸中反应。此外,(3a-c)与乙酸酐反应发生环缩合反应,生成 5-取代-3-苯基吲哚-2-噻唑并(2,3-b)-三唑(4a-c)。5-取代-3-苯基吲哚-2-[1,2,
