Abstract
A T∗T dimer with ∗ representing a 2′-OCH2CH2NHC(O)-4′ linkage connecting two nucleoside units was prepared by condensation of (S)-1-[2-(2-aminoethoxy)-3-(4,4′-dimethoxytrityloxy)propyl]thymine with 1,2-dideoxy-1-thyminyl-β-D-erythro-pento-furanuronic acid. The T∗T dimer was incorporated in oligodeoxynucleotides and investigated for hybridization to DNA.
