                                    β-Aminocyclopropanols were transformed, in a domino process catalyzed by Pd(II) salts, into the corresponding 2,3-dihydro-1H-pyridin-4-ones. Conversely the use of a Pd(0) derivative, Pd(dba)2, afforded the corresponding tetrahydropyrid-4-ones. The saturated derivatives were also obtained, in better yields, using Pd(II) and Cu(OAc)2 as stoichiometric oxidant.
