copper-catalyzed coupling method. The reactions of 2-haloanilines with a variety of α-amino acids in the presence of copper (I) iodide gave corresponding 3-substituted dihydroquinozalin-2-ones in up to 86% yield. Some new quinoxalin-2-ones (2, 4, 5, 13 and 16) have moderate cytotoxic activity toward HeLaS3 cell lines at 4.9–18.1 μM.
