Regioselective Stepwise Synthesis of Unsymmetrical 1,2,5-Triarylpyrroles via Palladium-Catalyzed Decarboxylative Cross-Coupling and C–H Arylation [PDF]
Pyrrole derivatives are natural organic molecules that are important to the pharmaceutical industry due to their occurrence in nature and their use in a wide range of medical applications. In general, non-symmetric, 1,2,5-triaryl-substituted pyrroles are

An Easy Synthesis of Monofluorinated Derivatives of Pyrroles from β-Fluoro-β-Nitrostyrenes
The catalyst-free conjugate addition of pyrroles to β-Fluoro-β-nitrostyrenes was investigated. The reaction was found to proceed under solvent-free conditions to form 2-(2-Fluoro-2-nitro-1-arylethyl)-1H-pyrroles.

Red-to-NIR Emissive Radical Cations Derived from Simple Pyrroles for Bio-Imaging [PDF]
Red-to-near-infrared (NIR) fluorophores are highly desirable for bio-imaging with advantages of excellent tissue penetration ability and less interference from auto-fluorescence, but their synthesis usually require tedious procedures and it’s thus highly
