A concise, novel and flexible metal‐free single step to synthesize functionalized quinolines is reported. Triflic anhydride‐mediated (Tf2O) activation of amides is discussed in the presence of pyridine to offer strong electrophiles, thereby showcasing excellent productivity, high regio‐ and chemoselectivity, and widely tolerable substrates. This approach provides a straightforward and efficient way
据报道,一种简洁,新颖且灵活的无金属一步法可以合成官能化喹啉。在吡啶的存在下讨论了三氟甲磺酸酐介导的(Tf 2 O)活化酰胺,以提供强亲电试剂,从而显示出优异的生产率,高区域选择性和化学选择性以及可广泛耐受的底物。该方法提供了构建氮杂杂环结构的直接有效的方法。
