sp3ectacularly mild! An efficient PdII‐catalyzed intramolecular dehydrogenative cyclization 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
