A palladium-catalyzed method employing different bulky biaryl phosphanes as ligands has been developed for the intramolecular amination of aryl bromides and iodides. A variety of aryl halide substrates have been aminated through the intramolecular pathway in good yield using different sugar-derived amines to give furo-benzoxa(thia)zepine and pyridoxazepine derivatives. The method is capable of furnishing
