The first example of copper catalyzed intramolecular N-arylation of hydroxamic acid derivatives is presented. Based on this transformation a new method for the synthesis of N-alkoxyindol-2-ones from 2-(2-bromoaryl)-acetylhydroxamates is developed. The reaction conditions tolerate standard hydroxyl protecting groups on the hydroxylamine moiety and are also applicable for the synthesis of six-membered N-alkoxybenzolactams.
