Abstract

This study presents a a straightforward synthetic approach to the specific pentacyclic bisindole structures related to fascaplysin alkaloids. The key transformation is an acid-promoted cascade involving a C–N bond formation/Mannich-type cyclization/dehydrogenation sequence. Nineteen novel bisindole derivatives bearing a wide range of functional groups were prepared by this method.
