A modular synthesis of polyfunctional dipyrrolemethanes is presented. Diverse side chains are introduced to 2-carboxypyrrole building blocks in two to four steps, resulting in a collection of substituted pyrroles that, when condensed in one step, give rise to diverse structural features.

characterized by a novel intramolecular Friedel−Crafts cyclization of an imino-pyrrole to prepare the azaindole core. Other key steps include a highly selective Horner−Wadsworth−Emmons olefination of a tricyclic ketone intermediate and subsequent catalytic asymmetric hydrogenation of a trisubstituted α,β-unsaturated ester to install the chirogenic center. Finally, a new indole sulfenylation protocol
