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 NaN3 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.

N-Carboalkoxy-2-nitrobenzenesulfonamides, readily prepared by acylation of 2-nitrobenzenesulfonamide (o-NsNH2), can be alkylated by either conventional or Mitsunobu protocols. Since the o-nosyl group can be deprotected under mild conditions, a variety of N-carboalkoxy derivatives of primary amines may be prepared in excellent yields from the corresponding alcohols and/or halides. In addition, allyloxycarbonyl (Alloc), t- butoxycarbonyl (t-Boc), and benzyloxycarbonyl (Cbz) groups can be deprotected in the presence of the o-nosyl group, allowing the resultant N-alkylated 2- nitrobenzenesulfonamides to be used for further preparation of secondary amines.
