A methodology for the syntheses of pyrimidine (C or U) 2-deoxyribonucleosides bearing bipyridine or terpyridine ligands attached via acetylene or phenylene linkers was developed based on single step cross-coupling reactions of unprotected 5-iodopyrimidine nucleosides with bipyridine or terpyridine acetylenes of phenyl boronates. The Sonogashira reactions with acetylenes were performed in DMF, while

The synthesis of 2,2'-bipyridinyl-2'-deoxyuridine metal-chelator nucleosides (Bipy-dU) with either ethynyl or ethylenyl linkers was now been accomplished. These new nucleosides will permit the construction of a number of corresponding metallo-DNA conjugates where many types of metals can be complexed to the 2,2'-bipyridinyl chelator group and the resulting metallo-dU conjugates incorporated into DNA
