Convenient synthesis of new heterocycles containing quinoxaline ring system

The aim of the current article was to describe simple procedures for the synthesis new heterocycles incorporating quinoxaline moiety using benzene-1,2-diamine and quinoxaline-2,3-dithiol as precursors. Simple synthetic methods were described for the synthesis of new heterocycles using commercially available chemicals. Also, the structures of the new compounds were determined using analytical and spectroscopic data including the single X-ray crystal structures. A series of new heterocycles containing quinoxaline nucleus were synthesized in good yields using simple and convenient procedures. A process has been described for the synthesis of new heterocycles containing quinoxaline moiety that might be difficult to be synthesized by other routes
