Abstract

Quinoxaline derivatives are an important class of nitrogen-containing heterocycles and they constitute useful intermediates in organic synthesis. 1 They have been reported for their applications in dyes, 2 pharmaceuticals, 3. and 4. and have also been used as building blocks for the synthesis of organic semiconductors. 5. and 6. 2,3-Substituted quinoxalines can be prepared by condensation of aryl-1,2-diamines and α-functionalized ketones, usually α-dicarbonyl compounds or ...
