Palladium-catalyzed benzylation of N-Boc indole boronic acids
摘要:
The direct benzylation of indole 2-boronic acid can be efficiently achieved using trans-PdBr-(N-Succ)(PPh(3))(2), alleviating the need for strong bases or toxic organotin reagents. Under these reaction conditions substituted indole-2-boronic acids and substituted benzyl bromides are cross-coupled to afford aryl(indolo)methanes in good yield. (C) 2010 Elsevier Ltd.
