  New strategy for the synthesis of N-aryl pyrroles: Cu-catalyzed C–N cross-coupling reaction of trans-4-hydroxy-l-proline with aryl halides

  摘要：

  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.

  A simple and efficient, ligand-free C-N cross-coupling of aryl halides/benzyl bromides with trans-4-hydroxy-L-proline has been developed to produce aromatized N-substituted pyrroles, using a catalytic amount of magnetically separable and recyclable CuFe2O4 nanoparticles, in the presence of Cs2CO3 in DMSO at 100 degrees C.
