Summary N-alkylated 2,5-diamino-p-benzoquinone-3,6-dicarboacidamides6 and7 are synthesized by alkylation and following reduction of 3,7-diamino-substituted benzodiisoxazoldiones1 c – f. Quinoneheterocycles2 a – b react under the presence of amines in a similar way to dioxobenzodiisoxazolium-salts3 and4 via intermediate formation of vinylogous, intramolecularly stabilized carbonylnitrenes to mono-, bi- and tricycled quinone-derivates8,9,11 and13 – 15.
