N2 - Some pyridazino[4,5-a][2.2.3]cyclazine-1,4(2H,3H)-diones (1a-d) as a luminescent compound were synthesized via several steps from indolizine derivatives. The key intermediates, dimethyl 6-dimethylamino[2.2.3]cyclazine-1,2-dicarboxylates (5, 7) were synthesized by the [8 + 2] cycloaddition reaction of 7-dimethylaminoindolizines (4, 6) with dimethyl acetylenedicarboxylate in the presence of Pd-C in refluxing toluene.
