Provided are a preparation method of a quinoline N-oxide derivative with an amide group capable of easily introducing the amide group into the quinoline N-oxide derivative by simplified processes and mild reaction conditions, and a quinoline N-oxide derivative with an amide group prepared by using the same.
Regioselective Introduction of Heteroatoms at the C-8 Position of Quinoline <i>N</i>-Oxides: Remote C–H Activation Using <i>N</i>-Oxide as a Stepping Stone
Reported herein is the metal-catalyzed regioselective C-H functionalization of quinoline N-oxides at the 8-position: direct iodination and amidation were developed using rhodium and iridium catalytic systems, respectively. Mechanistic study of the amidation revealed that the unique regioselectivity is achieved through the smooth formation of N-oxide-chelated iridacycle and that an acid additive plays
