WebMar 15, 2008 · The novel bridged nucleic-acid analogue 2‘,4‘-BNANC(2‘-O,4‘-C-aminomethylene bridged nucleic acid), containing a six-membered bridged structure with an N−O linkage, was designed and synthesized efficiently, demonstrating a one-pot intramolecular NC bond-forming key reaction to construct a perhydro-1,2-oxazine ring … WebDec 8, 2024 · Amido-bridged nucleic acids (AmNAs: AmNA [NR]) were previously designed by our group (Fig. 3) [ 40 ]. Since the C-N (amide) bond is generally shorter than a C-O bond in the bridge of 2′, 4′-BNA (LNA), AmNAs are expected to adopt a more rigid structure in comparison to 2′, 4′-BNA (LNA).
