Various 4-amino-2,3-dihydro-4H-triazoles with aromatic, aliphatic and heterocyclic substituents at the C(5) position were synthesized from corresponding esters and thiocarbohydrazide. This method allows the synthesis these heterocycles in a short time and at reduced expenses.
从相应的酯和硫代碳酰肼合成了各种在C(5)位置具有芳香,脂族和杂环取代基的4-氨基-2,3-二氢-4 H-三唑。该方法允许在短时间内以减少的费用合成这些杂环。
