## Abstract A general and efficient procedure for the synthesis of __N__βarylβsubstituted 4βpiperidones was developed. The two step syntheses proceeded with an overall yield of 60%β83% using __L__βproline as the ligand for the Cu(I)βcatalyzed Ullmann amination followed by subsequent hydrolysis of r
