trans-4-Hydroxy-L-proline is used for the first time as an effective nucleophilic coupling partner with aryl halides mediated by copper iodide with Cs(2)CO(3) as the base and DMSO as the solvent. Utilizing this protocol cross-coupling of trans-4-hydroxy-L-proline with a wide variety of substituted aryl halides to produce N-aryl pyrroles in moderate to good yields. (C) 2010 Elsevier Ltd.
