Bromination of quinoxaline and derivatives: Effective synthesis of some new brominated quinoxalines

The synthesis of brominated quinoxaline derivatives starting from several kinds of quinoxaline by different bromination strategies was studied. First the synthesis of some brominated quinoxalines was accomplished along with the development of an alternative and effective synthesis of some known compounds. A new, clean, and effective synthetic method for selective reduction of quinoxaline to 1,2,3,4-tetrahydroquinoxaline was also developed. The products obtained were characterized by means of NMR spectroscopy, elemental analyses, and mass spectrometry.

A facile bromination of hydroxyheteroarenes

Bromination of hydroxyheteroarenes using P2O5/Bu4NBr proceeds under mild conditions to afford high yields of various bromoheteroarenes. This procedure is successfully applied to large-scale syntheses of bromoheteroarenes.
