Condensation of ortho-aminophenols and N-benzylsulfonyl-o-phenylenediamine with nin-hydrin afforded tetracyclic products, the amino group entering into condensation with the carbonyl group at position 1 of ninhydrin. The structures of the reaction products were established by H-1 NMR spectroscopy and X-ray diffraction analysis.
