Synthesis and reactions of 1,6-dibenzoyl-5H,10H-diimidazo-[1,5-a;1′,5′-d]-pyrazine-5,10- dione

5,10-Dioxo-5H,10H-diimidazo[1,5-a;1′,5′-d]pyrazine-5,10- dicarboxylic acid dichloride in Friedel-Crafts reaction conditions formed with benzene the corresponding 1,6-dibenzoyl derivative 2, which reacted with alcohols and amines to give the keto esters and keto amides of 4(5)-benzoylimidazol-5(4)-carboxylic acids. The reaction of compound 2 with hydrazine gave substituted imidazo[4,5-f]pyridazine, and with o-phenylenediamine gave a derivative of imidazo[4,5-f]-1,4-benzodiazocine - a new heterocyclic system.
