Nine C 2 ‐symmetric chiral disulfonamides were designed and synthesized from L ‐valine, L ‐phenylalanine and L ‐leucine respectively via one‐pot ring opening of aziridines. The application of these disulfonamides as catalyst in the addition of diethyl zinc to benzaldehyde in three reagent systems: Ligand‐Ti(O i Pr) r ‐Et 2 Zn; Ligand‐Ti(O'Pr)d‐H z O‐Et 2 Zn; Ligand‐Et 2 Zn was also described.
