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.

compounds with indole, pyrrole, imidazole, and pyrazole nucleophiles via an allylic linker under neutral conditions is disclosed. This process enables the installation of an all-carbon quaternary center and new C–C and C–N bonds in a single operation. Despite the weakly acidic nature of N-heterocycles, the reactions proceed with good efficiency and complete regio- and chemoselectivity.
