title: Synthesis of 5-ethynyl-2'-deoxyuridine-5'-boranomono phosphate as a potential thymidylate synthase inhibitor.
abstract: The 5-ethynyl-2'-deoxyuridine nucleoside and the 5'-boranomonophosphate nucleotide were synthesized as analogs of 5-fluoro-2'-deoxyuridine monophosphate (5-FdUMP), a widely used mechanism-based inhibitor of thymidylate synthase. Synthesis was carried out from protected 5-iodo-2'-deoxyuridine and trimethylsilylacetylene by Sonogashira palladium-catalyzed cross coupling reaction followed by selective phosphorylation and finally boronation.
