- Synthesis method for azvudine
-
The invention discloses a synthesis method for azvudine. The method comprises the following steps of carrying out a hydroxyl substitution reaction on a compound 4 and an iodine elementary substance toobtain a compound 5, carrying out an elimination reaction on an iodo group in the compound 5 to obtain a compound 6, reacting the compound 6 with azide under the catalysis of ICl to obtain a compound7, carrying out an iodine substitution reaction on the compound 7 and carboxylic acid to obtain a compound 8, and carrying out an amino and hydroxyl deprotection reaction on the compound 8 to obtaina compound 9, namely the alzvudine. Compared with an existing synthesis method, the synthesis method has the advantages of short synthesis route, shortened reaction time, mild reaction conditions andeasily controlled reaction process, can be used for preparing the alzvudine with the lower cost, and has a very good application prospect.

- 132. Structural Comparison of Oligoribonucleotides and Their 2′-Deoxy-2′-fluoro Analogs by Heteronuclear NMR Spectroscopy
-
1-(2′-Deoxy-2′-fluororibofuranosyl)pyrimidines were synthesized and incorporated into an RNA oligonucleotide to give 5′-r[CfGCf(UfUfC fG)GCfG]-3′ (Cf: short form of Cd2′f2′ = 2′-deoxy-2′-fluorocytidine; Uf: short form of Ud2′f2′ = 2′-deoxy-2′-fluorouridine). The oligomer was investigated by means of UV, CD, and NMR spectroscopy to address the question of how F-labels can substitute 13C-labels in the ribose ring. Through-space (NOE) and through-bond (scalar couplings) experiments were performed that make use of the ameliorated chemical-shift dispersion induced by 19F as an alternative heteronucleus. A comparison of the structures of fluorinated vs. unmodified oligomer is given. It turns out that the fluorinated oligonucleotide exists in a 14:3 equilibrium between a hairpin and a duplex conformation, in contrast to the unmodified oligonucleotide which predominantly adopts the hairpin conformation. Furthermore, the fluorinated hairpin structure adopts two distinct conformations that differ in the sugar conformation of the Uf5 and Cf6 nucleoside units, as detected by the 19F-NMR chemical shifts. The role of the 2′-OH group as stabilizing element in RNA secondary structure is discussed.
