Abstract :
The synthesis of a new brick heterocyclic system of quinoxaline was developed by a cyclocondensationreaction starting from o-phenylenediamine derivatives. Thus6 chloroquinoxaline-2,3(1H,4H)–dione was obtainedin excellent yield by condensation of4-Chloro-o-phenylenediamine with oxalic acid at reflux in a hydrochloric acid solution.Thealkylationreactions werethen carried out and optimized by using monohalogenated agentsunder phase transfer catalysis conditions. The reaction studied lead to the expected productsin good yields and the structures of various obtained compounds are easilydetermined by theusual spectroscopic methods. This kind of products can show a potent pharmacological andtherapeutic activitiesas given in the studies reported in the literature.
