An easy strategy for the synthesis of tetraethyl‐2‐(3‐mercapto‐4H‐1,2,4‐triazol‐4‐ylamino)‐2‐(aryl)ethane‐1,1‐diyldiphosphonate and tetraethyl‐(6‐(aryl)‐5,6‐dihydro[1,2,4]triazolo[3,4‐b]‐[1,3,4]thiadiazol‐6‐yl)methylenediphosphonate derivatives with reasonable 67–85% overall yields has been developed. The approach was achieved via applying Wadsworth–Horner–Emmons reagent, tetraethylmethylenebisphosphonate
合成四乙基-2-(3-巯基-4 H -1,2,4-三唑-4-基氨基)-2-(芳基)乙烷-1,1-二基二膦酸酯和四乙基-(6- (芳基)-5,6-二氢[1,2,4]三唑[3,4- b ]-[1,3,4]噻二唑-6-基)亚甲基二膦酸酯衍生物的总收率合理在67-85%发达。该方法经由施加沃兹沃思-霍纳-埃蒙斯试剂,tetraethylmethylenebisphosphonate,实现以4-(arylideneamino)-4 ħ-1,2,4-三唑-3硫醇在相转移催化条件下 据报告对17种亚甲基-1,1-双膦酸酯产品中的12种进行了抗菌效力筛选结果。与阳性对照相比,测试的噻二唑亚甲基双膦酸酯中的两种显示出对病原体的更好的抗菌活性谱。
