5-hydroxyindoles were not obtained from this diquinone. It yielded similar reaction products of the Nenitzescu reaction like other quinones activated by two electron-withdrawing groups. Furthermore, these new compounds 8A were found to constitute precursors for the synthesis of azonines. The conversion to dibenzoazonines 13 occurred in an unusual and up to now unknown way consisting of isomerization, ring opening
