Copper-catalyzed highly regioselective 2-aryloxylation of 2,x-dihalopyridines
摘要:
2,x-Dihalopyridines reacted with phenols catalyzed by CuI/TMEDA in the presence of Cs2CO3 in DMSO at 110 degrees C under nitrogen atmosphere for 24 h to afford 2-aryloxypyridines in good to high yields except p-nitrophenol. To expand this methodology, a vanilloid receptor ligand used in treatments was prepared in good yield. This method has potential utility in the synthesis of pharmaceuticals, agrochemicals and even natural products. (C) 2012 Elsevier Ltd. All rights reserved.
