Two novel enantiopure 1-benzyl-2-aziridinesulfinimines bearing a chiral group on both sides of the carbon-nitrogen double bond were synthesized from the condensation of racemic 1-benzyl-2-aziridinecarboxaldehyde and enantiopure p-toluenesulfinamide. The addition reaction with phosphite anion followed by the ring-opening reaction with thiophenol provided chiral α,β-diamino-phosphonic acid derivatives. The addition reactions showed the operation of a double-stereo-differentiation effect. The possible transition states of the reaction were proposed, and high diastereoselectivities of the addition reactions of phosphite anions to both aziridinesulfinimines were realized in the presence or absence of zinc bromide.
