Synthesis of a Carboxamide Linked UBr∗UBrDimer–Duplex and Triplex Stabilities of the Corresponding Oligodeoxynucleotides

Abstract A UBr∗UBr dimer was synthesized by connecting the appropiate nucleoside monomers through a 5-atom carboxamide linkage. The dimer was incorporated in oligodeoxynucleotides and investigated for hybridization properties toward single and double stranded DNA.
