A simple and efficient method for the synthesis of β-aminoacryaldehydes via Cu(OAc)2·H2O and FeCl3 cocatalyzed Meyer–Schuster-Like rearrangement of propargylic amines was developed. The reactions proceed selectively as the E-isomers in generally good yields under aerobic conditions, and are compatible with a broad range of functional groups. This method combines C–N bond cleavage as well as the N-aryl
