Abstract

Transformation of 3-amino-8-hydroxy-1,6-dioxo-2,7-diazaspiro[4.4]non-3-en-4-carbonitriles in concentrated hydrohalic acid media leads to the obtaining of two classes of fused heterocycles: 4-halogen-3-hydroxy-1,3-dihydrofuro[3,4-c]pyridin-1-ones and octahydropyrrolo[3,4-c]pyrrole-1,3,4,6-tetraones.
