Chiral-4′-Methyl-α‑(l)‑Threofuranosyl Nucleic Acids: Synthesis, Structure, Binding Affinity, Nuclease Resistance, and Polymerase Recognition
α-(l)-(3′–2′)-Threofuranosyl nucleic acid (TNA) cross-pairs with DNA and RNA and is not degraded by nucleases and thus has potential for use in diagnostics and therapeutics based on nucleic acids. Here, we describe the synthesis of 15 building blocks of chiral 4′-(R)- and 15 building blocks of chiral (S)-methyl-α-(l)-t...
