hydrate, phenacyl bromide, or hydrazonoyl chlorides afforded 1,2,4-triazole, 1,3-thiazole, and 1,3,4-thiadiazoles. Reaction of 1,2,4-triazole with phenacyl bromide or hydrazonoyl chlorides afforded the corresponding 1,2,4-triazolo[3,4-b][1, 3, 4]-thiadiazines. All these new compounds were screened for antibacterial and antifungal activity. Some had promising activity. Graphical abstract
摘要通过在氢氧化钾存在下用二硫化碳处理酰肼来制备肼基二硫代硫酸钾。该钾盐与水合肼,苯甲酰溴或酰肼基氯反应,得到1,2,4-三唑,1,3-噻唑和1,3,4-噻二唑。1,2,4-三唑与苯甲酰溴或酰肼基氯反应,得到相应的1,2,4-三唑并[3,4- b ] [1、3、4]-噻二嗪。筛选所有这些新化合物的抗菌和抗真菌活性。有些活动前景良好。 图形概要
