Synthesis of a triazole-linked 3'-5' thymidine dimer making use of 1,3-dipolar cycloaddition is described. The azido-precursor was obtained by regioselective chlorination of thymidine, followed by azidation. The second precursor, a propargyl derivative, was obtained by selective 3'-O-alkylation of thymidine. Two 'click systems' were compared to obtain the desired dimer. These reactions were performed by microwave irradiation. (c) 2007 Elsevier Ltd. All rights reserved.
