Quinoxaline derivatives are an important class of nitrogen containing heterocycles
and have been widely used in dyes pharmaceuticals and electrical/photochemical
materials. Also, quinoxaline ring moiety is a part of various antibiotics such as
Echinomycin, Levomycin, and Actinoleutin that are known to inhibit growth of gram
positive bacteria, and are active against various transplantable tumors [1]. Also,
dicyanopyrazine derivatives have been synthesized and are valuable in a broad range
of chemistry fields due to their applications as functional dyes, nonlinear optical
materials, etc. [2]. Because of their importance, up to now, several methods have been
reported for the synthesis of these compounds including the condensational reaction
of an aryl 1,2-diamine with a 1,2-dicarbonyl compound in refluxing or in the presence
of an acid catalyst under various reaction conditions [3].
