Cu(I)-Catalyzed Highly Regioselective C–H Amidation\nof Quinoline <i>N</i>‑Oxides with Dioxazolones

A Cu(I)-catalyzed\nhighly regioselective synthesis of 2-acetamidequinoline <i>N</i>-oxides using dioxazolones with quinoline <i>N</i>-oxides\nhas been reported. The reaction possesses mild reaction conditions\nand excellent functional group compatibility. Furthermore, the addition\nof hydrochloric acid promotes the decomposition of copper complexes,\nwhich is beneficial for postprocessing.
