sp3ectacularly mild! An efficient PdII‐catalyzed intramoleculardehydrogenativecyclization of imines affords (dihydro)pyrrole products using molecular oxygen as the sole oxidant. This mild formal sp3‐CH functionalization allows rapid and atom‐economical assembly of (dihydro)pyrrole rings from inexpensive and readily available allylamines and ketones. A broad range of functional groups are tolerated

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.
