Graphical Abstract

Up the tempo: The intramolecular addition of oxime radicals to CC bonds was achieved by using DEAD and TEMPO to give 4,5-dihydroisoxazoles as a result of a CO bond-forming, 5-exo-trig cyclization. γ,δ-Unsaturated ketoximes also reacted to afford cyclic nitrones through CN bond formation. The reactions offer a metal-free approach for the vicinal difunctionalization of unactivated alkenes.
