Intramolecular Aminoazidation of Unactivated Terminal Alkenes by Palladium-Catalyzed Reactions with Hydrogen Peroxide as the Oxidant

The palladium-catalyzed aminoazidation of aminoalkenes yielding azidomethyl-substituted nitrogen-containing heterocycles was developed. The procedure requires oxidative conditions and occurs at room temperature in the presence of hydrogen peroxide and NaN 3 as the azide source. These conditions provide selective exo -cyclization/azidation of the carbon–carbon double bond, furnishing a versatile approach toward five-, six-, and seven-membered heterocyclic rings.
