protected chiral functionalised bis-aziridines, prepared from D-mannitol, are opened by various organometallic reagents (organomagnesium,-lithium and -copper derivatives) as well as by heteronucleophiles (N3-, Br-, Cl-, HS-, PhS-). Orientation of the reaction toward diopening (route to enantiomerically pure α-amino acids) or toward heterocyclisation (route to chiral, polysubstituted piperidines) is
