N-Protected trifluoromethyl-substituted sulfoximines have been prepared by treatment of sulfonimidoyl fluorides with a combination of the Ruppert−Prakash reagent (TMSCF3) and tetrabutyl ammonium fluoride (TBAF). The starting materials were accessed following two synthetic routes, and for each reaction sequence the substrate scope was evaluated. Accordingly, a wide variety of aryl-substituted products
通过用Ruppert-Prakash试剂(TMSCF 3)和四丁基氟化铵(TBAF)的组合处理磺酰亚胺基酰氟,可以制得受N保护的三氟甲基取代的亚磺酰亚胺。遵循两种合成路线获取起始原料,并针对每个反应顺序评估底物范围。因此,以中等至良好的产率获得了多种芳基取代的产物。
