A copper‐catalysed (diacetoxyiodo)benzene‐promoted aerobic esterification reaction of acetoacetamides was developed for the synthesis of oxamates, which are useful precursors in synthetic organic chemistry. This practical and mild synthetic approach proceeded at 25 °C under open‐air conditions and afforded methyl 2‐oxo‐2‐(phenylamino)acetates in good to excellent yields combined with C−C σ‐bond cleavage
