## Abstract β‐Sultams, biologically interesting sulfonyl analogues of β‐lactams, have been prepared by an organocatalytic asymmetric formal [2+2]‐cycloaddition approach of non‐nucleophilic imines with alkyl sulfonyl chlorides. In the case of very electron poor N‐tosyl imines derived from chloral or
