Ni(0)–Cu(i): a powerful combo catalyst for simultaneous coupling and cleavage of the C–N bond with cyclization to valuable amide-based pyrroles and 4-pyridones†
Abstract
Unprecedented ligand-tuned Ni(0)–Cu(I) combo catalysis is demonstrated via sequential bond activated domino C–N/C–C coupled annulation with C–N bond cleavage to afford valuable polysubstituted amide-based pyrroles and 4-pyridones selectively from β-ketoanilides.
