Allylic sulfamides undergo aerobic oxidativecyclization at room temperature, mediated by a Pd(O2CCF3)2/DMSO catalyst system in tetrahydrofuran. The cyclic sulfamide products are readily converted into 1,2‐diamines, and substrates derived from chiral allylic amines cyclize with very high diastereoselectivity.
