A radical-mediated approach to alkene hydration is described. The present strategy capitalizes on the unique radical reactivity of hydroxamicacids, which are capable of functioning as both synthetically useful oxygen-centered radical species and suitable hydrogen atom-based donors. This reaction manifold has been applied to both alkene hydrations and tandem alkene–alkene carbocyclization processes

N-Alkyl-2,2-dimethyl-3-butenohydroxamic acids and their cyclic derivatives were halocyclized by iodine monochloride, N-bromosuccinimide, or N-chlorosuccinimide to afford the corresponding 2-alkyl-4,4-dimethyl-5-halomethylisoxazolidinones and 5-membered ring fused isoxazolidinones in excellent yields.

A radical-mediated approach to metal-freealkene oxyamination is described. This method capitalizes on the unique reactivity of the amidoxyl radical in alkene additions to furnish a general difunctionalization using simple diisopropyl azodicarboxylate (DIAD) as a radical trap. This protocol capitalizes on the intramolecular nature of the process, providing single regioisomers in all cases. Difunctionalizations
