Quinine-catalyzed enantioselective desymmetrization of meso-aziridines with benzenethiols

Ring opening of meso-aziridines with benzenethiols utilizing quinine as an organocatalyst has been developed. The reaction proceeded smoothly in the presence of 10 mol % of quinine in CHCl3 to afford β-amino sulfides in high yields and with moderate to good enantioselectivities.
