Popis:	Diels-Alder adducts were formed in the lead tetraacetate oxidations of substituted cyclic hydrazides of furan, pyridazine and pyrrole dicarboxylic acids in the presence of 1,3-cyclo-hexadiene or 1,3-cyclopentadiene. The products resulting were furo[3,4-g]pyridazino[1,2-a]-pyridazine-6,10-diones, pyridazino[4,5-g]pyridazino[1,2-a]pyridazine-6,11-diones, and pyrrolo-[3,4-g]pyridazino[1,2-a]pyridazine-6,10-diones, respectively. Some hydrogenations and ring opening reactions were studied.
