Copper‐Promoted Oxidative Amidation of Imines: A Facile Route to Amides.

Herein, an environmentally friendly and efficient amidation method of imines by Oxone and CuO has been developed. This facile method shows excellent selectivity without affecting other functional groups such as phenyls, halogens, cyans, esters or heterocycles. This method features a broad substrate scope, mild conditions and high yields (≤90 %), and the yield in the gram scale experiment also reaches up to 81 %. Flonicamid, moclobemide and bupivacaine are also successfully synthesized to demonstrate its potential utilities. [ABSTRACT FROM AUTHOR]
