By reduction of the 3,7-diamino-substituted heterocycles 1c-d and 6a-d, the quinoid 2,5-diamino-3,6-dioxocyclohexa-1,4-diene-1,4-dicarboxamides 2c-h and 7a-d are synthesized.The diaminodicarboxamides 2 can be recyclised by use of Pb(OAc)4.The dialkylamino-substituted derivatives 1c-h react with NaBH4 under conservation of the heterocyclic system to the tetrahydro-benzo<1.2-c:4,5-c'>diisoxazolidiones of type 5.The NMR-spectroscopic behavior of 2 and 7 is discussed.
