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

Vincze, Zoltan,Biro, A. Beatrix,Csekei, Marton,Timari, Geza,Kotschy, Andras

, p. 1375 - 1385 (2007/10/03)

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.
