In this paper we report the synthesis of novel S-alkenyl derivatives of 5-(trifluoromethyl)-4H-1,2,4-triazole-3-thiol via alkenation reaction with different alkenyl halides. Reaction between the resulting S-alkenation products and iodine proceeds regiospecifically to give new fused fluorine- and iodine-containing [1,2,4]triazolo[3,4-b][1,3]thiazine heterocyclic systems. The structure of synthesized
在本文中,我们报告-5-(三氟甲基)-4的新颖S-烯衍生物的合成ħ经由与不同烯基卤化物反应alkenation -1,2,4-三唑-3-硫醇。所得S-alkenation产品和碘之间的反应进行区域专一性,得到新的稠合的含氟和含碘[1,2,4]三唑并[3,4- b ] [1,3]噻嗪的杂环系统。合成的化合物的结构通过质谱,IR,确认1个H,13 C和19 F NMR光谱包括二维1 H- 13 ÇHSQC,1 H- 1 ħCOSY,1 H- 13ÇHMBC相关性,元素分析和单晶X射线衍射研究。
