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. Georg Thieme Verlag Stuttgart.

Synthesis of (±)-cathaformine

The structure previously assigned to the N-(methoxycarbonyl)aporphine alkaloid (+)-cathaformine has been confirmed by a total synthesis of the racemic substance in which the key step involved formation of ring c by a radical-initiated cyclization. CSIRO 2
