A new amide bond activation paradigm through amino acid insertion enabled by two tandem intramolecular rearrangements is reported. This strategy only requires stable and readily available amide and amino acid as the starting materials, which does not need any pre-functionalization as well as the isolation of reaction intermediates.

We successfully developed a nickel-catalyzed transamidation method for the ringopening of N-acyl lactams. The method involves a reaction between N-benzoylpyrrolidin-2-one derivatives and aniline derivatives, with Ni(PPh3)2Cl2 serving as the catalyst, 2,2′-bipyridine as the ligand, and manganese as the reducing agent. This reaction led to the formation of ring-opening-amidated products in good yields
