Lai's protocol for the synthesis of nitroxides has been extended to the synthesis of several newchiral piperazine and morpholine nitroxides. This strategy utilizes the Bargellini reaction as the key bond-forming step. Several optically pure nitroxides incorporating alpha-aromatic and alpha-spiro centers were prepared by this route. These chiral nitroxides will be of interest as enantioselective oxidants
