Palladium-Catalyzed Oxidation of Amino Alkenes to Cyclic Imines or Enamines and Amino Ketones

Amino alkenes of the type CH2=CH(CH2)nNH2 (n = 3,4) are cyclized to pyrrolines or piperideines under ''Wacker process''conditions.Amino alkenes with a secondary amino group yield the corresponding cyclic enamines, while tertiary amino alkenes give amino ketones.
