A short synthesis of N-substituted 3,4-diarylpyrroles by condensation of a phenacyl halide with a primary amine and a phenylacetaldehyde is reported. The key step is an intramolecular cyclization of an in situ generated enamine onto a ketone. Using differently substituted aromatic reactants and N-(3-aminopropyl)azatricyclodecane as the amine component, the preparation of analogs of the cytotoxic marine
