Abstract

Upon reaction of 4-oxo-5-hydroximino-4,5,6,7-tetrahydrobenzofurazan and -tetrahydrobenzofuroxan with enamines, derivatives of N-oxides of tetrahydropyrrolo[2,3-e]benzofurazan are formed. Upon action of acids on these compounds, we observe formation of derivatives of indole and 1-hydroxyindole, annelated with the furazan and furoxan rings.
