An efficient method for the synthesis of 6-arylpurines (nucleosides) was developed via Suzuki-Miyaura cross-coupling reactions of 6-chloropurines (nucleosides) and sodium tetraarylborate in neat water (ethanol). The process gave good to high isolated yields within a short reaction time under microwave irradiated conditions. (C) 2011 Elsevier Ltd. All rights reserved.
