An efficient new method to synthesize α-oxy N-acyl aminals and hemiaminals in a single step from readily synthesized N-acyl enamines has been developed using PhI(OAc)2 as the oxidant. The reaction conditions are very mild and the products are obtained in good yields (65–92%). A possible mechanistic pathway is laid out.
