We describe (i) a simple method for the synthesis of C5-modified nucleosides from 5-iodo-2'deoxyuridine and (ii) their activity against six types of human cancer cell lines (HCT15, MM231, NCI-H23, NUGC-3, PC-3, ACHN). We generated nitrile oxides in situ from oximes using a commercial bleaching agent; their cycloadditions with 5-ethynyl-2'-deoxyuridine yielded isoxazole derivatives possessing activity against the cancer cell lines. We synthesized several azides from benzylic bromides and their click reactions with 5-ethynyl-2'-deoxyuridine provided triazole derivatives. (C) 2009 Elsevier Ltd. All rights reserved.
