The C2-symmetric bis(aziridine) ligands 1 -5 have been screened in the enantioselective addition of organolithium reagents to imines. Ligand 1 (used in stoichiometric amounts) was found to be superior in terms of chemical yield and enantioselectivity, the best result being 90\*70 yield and 89% e.e.
