Abstract

The synthesis of azanaphthoquinone annelated pyrrole derivatives is described. The [c]-annelated derivative was synthesized by reaction of an azanaphthoquinone monoketal with tosylmethyl isocyanide. The synthesis of each of the two isomeric [b]-annelated pyrrole derivatives was realized by selective acylation reactions with pyrrole. Furthermore detailed NMR spectroscopic studies (1H, 13C) are published.
