Sels d'aziridinium stables c-fonctionnalisés II: Stéréochimie de la quaternisation,synthèses stérèodirigées de composés n-trideutériométhylés et attribution de leurs configurations relatives par el'fet overhauser nucléaire

Aziridines bearing a functionality on a ring carbon and an alkyl or deuteriomethyal group on nitrogen have been quaternized at different temperatures. The configurations of the resulting, stable, diastereomeric aziridinium ions have been assigned by Nuclear Overhauser effect. The stereoselectivity in quaternization is discussed.
