Two oxathiozolidine‐S‐oxide templates have been developed and used in a four‐component coupling protocol for the synthesis of a wide range of chiral sulfinimines in high enantiomeric excesses. The templates can be synthesized from cheap commodity chemicals in three steps in high yields. Furthermore the template is easily recovered in high yields for recycling.
