  Nucleosides. LVI¹Synthesis and Chemical Modifications of 3′-Deoxy-Pyrimidine Nucleosides

  摘要：

  3'-Deoxyuridine(1) and 3'-deoxycytidine(2) were prepared with improved yields by two different methods applying either the Barton procedure to appropriate 2',5'-di-O-protected pyrimidine nucleosides or by choosing the direct glycosylation of the pyrimidine bases with 1,2-di-O-acetyl-5-O-toluoyl-3-deoxy-D-erythro-pentofuranose via the silylation approach. Suitable protecting groups for the sugar moiety have been found in the trityl, tert-butyldimethylsilyl and the thexyl groups which are inert in the radical deoxygenation process. The newly synthesised compounds were characterised by elemental analyses and UV and H-1-NMR spectra.

  oligonucleotides and RNA had stability similar to unmodified RNA-RNA duplexes (Delta t(m)= -0.2 to +0.7 degrees C per modification). However, the AM2 modification resulted in substantial stabilization of duplexes: Delta t(m)= +1 to +2.4 degrees C per modification compared to all RNA. A 2'-O-methyl vicinal to the AM2 linkage further increased the duplex stability. Our results suggest that RNA analogues having

  Amide linked ribonucleoside dimer 5 was prepared and converted into selectively protected H-phosphonate building block 9. Oligoribonucleotide duplexes having amide linkages at selected sites were synthesized and their stability was studied by UV melting experiments.
