Some new N-glycosides of 4-(2-phenylethyl)-5-pyridyl-1,2,4-triazole-3-thiones were synthesised by the coupling reaction of halo sugar with 4,5-disubstituted 3H-1,2,4-triazole-3-thiones in the presence of mercuric cyanide and dry nitromethane as solvent, followed by deprotection using dry ammonia in methanol. All ofthe above compounds were fully characterized by means of infrared, 1 H NMR spectroscopy
4-(2-苯乙基)-5-吡啶基-1,2,4-三唑-3-硫酮的一些新的N-糖苷是通过卤代糖与4,5-二取代3H-1,2的偶联反应合成的, 4-三唑-3-硫酮在氰化汞和无水硝基甲烷作为溶剂存在下,然后使用无水氨的甲醇溶液脱保护。所有上述化合物均通过红外、1 H NMR光谱、质谱和元素分析进行了充分表征。
