Scope and limitation of the reductive cleavage reaction of a-aminoketone systems with zinc-acetic acid are described. The carbon-nitrogen bond cleavage reaction was applicable to a wide range of alpha-aminoalkyl aryl ketones possessing various substituents on the aromatic ring. In contrast, a-aminoalkyl alkyl ketones with protons at the alpha'-position or alpha-aminoesters were sluggish to the carbon-nitrogen cleavage reaction.
