Facile synthesis of 9-azajulolidine and its application to post-Ullmann reactions

This Letter describes the efficient synthesis of 9-azajulolidine from readily available reagents and its utilization as an effective electron-rich ligand for post-Ullmann-type reactions, that is, for C(aryl)–heteroatom (N, O, S) bond formation reactions, with dramatically enhanced reaction rates.
