We report on the synthesis of 1,2,4-triazoles substituted with 2 or 3 amino acid side chains, using silver benzoate as a key reagent for the cyclization step. A complete study of the optical purity retention during the synthetic process leading to these compounds is described. In addition an improved work-up after the addition-cyclization step was also established leading to better yields and metal-free
我们报道了用苯甲酸银作为环化步骤的关键试剂,合成了被2或3个氨基酸侧链取代的1,2,4-三唑。描述了在合成过程中导致这些化合物的光学纯度保持率的完整研究。此外,还建立了加成环化步骤后的改进后处理,从而提高了产量并生产了不含金属的产品。
