Nonplanar, electronically destabilized amides are powerful intermediates in organic synthesis. A highly selective method for transamidation of common secondary amides under mild, metal-free conditions relies on transient N-selective functionalization to weaken amidic resonance. This procedure accomplishes challenging transamidation of secondary amides under mild conditions.
