A 'one-pot' method has been developed for the synthesis of azoquinazolinones from substituted 2-halobenzamides and different N-heterocycles via Cu(I)-catalyzed C-N coupling/C-H activation/C-N formation process under O-2. A number of azoquinazolinones containing different azole rings and substituents were obtained in good yields. (C) 2013 Elsevier Ltd. All rights reserved.
