Polyheterocycles are found in many natural products and are useful moieties in functional materials and drug design. As part of a program towards the synthesis of Stemona alkaloids, a novel palladium(II)‐catalyzed CH activation strategy for the construction of such systems has been developed. Starting from simple 1,3‐dienyl‐substituted heterocycles, a large range of polycyclic systems containing pyrrole
The van Leusen pyrrole synthesis was used to assemble three potential precursors of porphobilinogen, one of which was converted to the natural product using a new method for the direct alkylation of beta-hydroxymethylpyrroles. (C) 1997 Elsevier Science Ltd.
