4-Bromo-6-fluoro-2-(trifluoromethyl)quinoline and 4-bromo-7-fluoro-2-(trifluoromethyl)quinoline were selected as model substrates to explore under what conditions regiochem. exhaustive functionalization reactions can be carried out. This goal was achieved by using trimethylsilyl entities and iodine atoms as the sole auxiliary substituents. The organolithium intermediates could be generated and the
选择 4-Bromo-6-fluoro-2-(trifluoromethyl)quinoline 和 4-bromo-7-fluoro-2-(trifluoromethyl)quinoline 作为模型底物,探索在什么条件下 regiochem。可以进行彻底的官能化反应。这个目标是通过使用三甲基甲硅烷基实体和碘原子作为唯一的辅助取代基来实现的。可以生成有机锂中间体并去除保护基团,而不会损害存在于 4 位的溴原子。[在 SciFinder (R) 上]
