  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.

  that of the natural products. Elucidation of stereochemistry in the pacidamycins has been completed through a campaign of natural product degradation experiments in combination with the total synthesis of the lowest-molecular weight dihydropacidamycin, dihydropacidamycin D. The stereochemical identities of the tryptophan and two alanine residues contained in pacidamycin D have been shown to be of the

  A series of 2'-C-cyano-2'-deoxy- and 2'-C-cyano-2',3'-dideoxy arabinofuranosyl nucleosides have been prepared by reaction of the corresponding 2'-ulosyl- and 3'-deoxy-2'-ulosyl nucleosides with sodium cyanide followed by 2'-deoxygenation of the cyanohyrins formed and removal of the protecting groups of the sugar moiety.
