Indole-2-carboxylic acid hydrazide was prepared and allowed to react with aromatic aldehydes in acidic medium to give the corresponding hydrazone derivatives in good yields. The hydrazones were cyclized to indolo[2,3- d ]pyridazine derivatives by refluxing with acetyl chloride. The indole carbohydrazide was converted to 2-triazolylindoles which acted as starting materials for several indole derivatives
制备吲哚-2-羧酸酰肼,并使其在酸性介质中与芳族醛反应,以高收率得到相应的衍生物。通过与乙酰氯回流,将hydr环环化为吲哚[2,3- d ]哒嗪衍生物。吲哚碳酰肼被转化为2-三唑基吲哚,这是几种吲哚衍生物的起始原料。还制备了许多新的吲哚衍生物并进行了结构确认。
