  • Title: Copper-catalyzed domino synthesis of quinazolinones via Ullmann-type coupling and aerobic oxidative C-H amidation.
    Author: Xu W, Jin Y, Liu H, Jiang Y, Fu H.
    Journal: Org Lett; 2011 Mar 18; 13(6):1274-7. PubMed ID: 21344914.
    Abstract:
    An efficient copper-catalyzed approach to quinazolinone derivatives has been developed, and the protocol uses cheap and readily available substituted 2-halobenzamides and (aryl)methanamines as the starting materials as well as economical and environmentally friendly air as the oxidant. This can be the first example of constructing N-heterocycles via sequential Ullmann-type coupling under air and aerobic oxidative C-H amidation.
