A New Method for Regioselective Introduction of Trifluoromethyl Groups into Heteroarenes; Part2. Nucleophilic Substitution of 5-Fluoro-4- trifluoromethyl-1,3-azoles 5-Fluoro-4-trifluoromethyl-1,3-azoles are readily susceptible to nucleophilic displacement reactions at C-5. With binucleophiles, the reactioncan be used for linking trifluoromethyl-substituted 1,3-azoles to aromatic, heteroaromatic, and heterocyclic systems, linearly or angularly,directly or across various bridging groups respectively.
一种新的区域选择性引入三氟甲基至杂环化合物的方法;第二部分:5-氟-4-三氟甲基-1,3-噻唑的亲核取代反应
5-氟-4-三氟甲基-1,3-噻唑容易在C-5位发生亲核取代反应。与双亲核试剂反应时,该反应可用于将三氟甲基取代的1,3-噻唑线性或角度性地直接或通过各种桥连基团连接到芳香、杂芳香及杂环系统上。
