Pentrabromopseudilin and other 2 and 3-arylpyrrole derivatives were synthesized through the Heck–Matsuda reaction involving endocyclic enecarbamates and N-protected 3-pyrrolines, respectively. The overall processes permitted an easy and efficient access to these structural motifs present in several bioactive compounds. Attempts to synthesize the compound isopentabromopseudilin led to a tribromo aryl
A sequential radical decarboxylation–oxidation–iodination–arylation process allows the metal-free, direct conversion of proline derivatives into 2-aryl-3-iodopyrrolidines, which are valuable precursors of a variety of heterocycles.
