Regioselective intermolecular radical carboaminoxylation using various alkoxyamines are presented. These environmentally benign tin-free radical additions can either be performed under microwave conditions at 180 °C or by using conventional heating at 125 °C. Intermolecular Trost-Tsuji allylation of the carboaminoxylation products provide five- and six-membered carbocycles in moderate to good yields. The radical addition/Pd-catalyzed intramolecular allylation can be performed as one-pot process.
