Özet

Unsaturated bicyclic endoperoxides were reacted with dimethyl 1,2,4,5-tetrazine-3,6-dicarboxylate. The Diels-Alder addition products 6-10 were isolated and characterized, The primary formed addition products gave the corresponding 1,4-dihydropyridazine derivatives upon extrusion of nitrogen. Pyridazine endoperoxides were synthesized by oxidation of the corresponding 1,4-dihydropyridazine derivatives with PIFA.
