The palladium-catalyzed preparation of condensed tetracyclic heterocycles and their application to the synthesis of rac-mangochinine

Dihydroisoquinoline derivatives and their analogues, prepared by the Bischler-Napieralsky reaction, were converted to their indole-fused derivatives. Scope and limitations of the palladium-catalyzed reaction, proceeding through the tautomeric enamine forms of these compounds, were studied and the process was extended to the preparation of racemic mangochinine.
