pharmaceutically important α-amino ketonesfrom readily available α-hydroxy ketones and secondary amines through a tandem reaction sequence based on Heyns rearrangement. The reaction smoothly proceeded by using catalytic PTSA as catalyst without solvent. Primary and secondary α-hydroxy ketones were readily used and regioselectively afforded the correspondingly α-amino ketones with moderate yield.
