  Copper-catalyzed intramolecular N-arylation of ureas in water: a novel entry to benzoimidazolones

  摘要：

  The copper-catalyzed intramolecular N-arylation of 2-bromoarylureas performed in water leading to the benzo[d]imidazolone framework is reported. The scope of the methodology presented herein proved to be broad and afforded a significant number of benzoimidazolones in good to excellent yields. The reported protocol is based on the use of Cut and TMEDA acting both as the ligand and as the base in a water solution, which allows for the easy separation of the catalyst containing aqueous phase from the products by simple extraction. Additionally, the N- versus O-arylation competitive processes are also discussed. (c) 2008 Elsevier Ltd. All rights reserved.

• Regioselective Synthesis of Benzimidazolones via Cascade C–N Coupling of Monosubstituted Ureas

  A direct method for the regioselective construction of benzimidazolones is reported wherein a single palladium catalyst is employed to couple monosubstituted urea substrates with differentially substituted 1,2-dihaloaromatic systems. In this method, the catalyst is able to promote a cascade of two discrete chemoselective C-N bond-forming processes that allows the highly selective and predictable formation of complex heterocycles from simple, readily available starting materials.
