  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.
