  Preparation of 2′- and 3′-bromo derivatives of 2′,3′-unsaturated uracil and adenine nucleosides has been carried out starting from the corresponding β-hydroxyselenides by way of bromination and successive selenoxide elimination. These compounds have been shown to serve as versatile synthons for the preparation of anti-HIV candidates, 2′-C- and 3′-C-branched 2′,3′-unsaturated nucleosides, through palladium-catalyzed

  A general total synthetic method for the stereocontrolled synthesis of 2',3'-dideoxy- as well as 2',3'-didehydro-2',3'-dideoxynucleosides is presented. Introduction of an alpha-phenylselenenyl group at the 2-position of 2,3-dideoxyribosyl acetate directs the glycosyl bond formation to give greater-than-or-equal-to 95% beta-isomer. This 2'-phenylselenenyl nucleoside may be converted to either the 2',3'-dideoxynucleoside by treatment with n-Bu3SnH and Et3B at room temperature or to the unsaturated derivative by treatment with H2O2/cat. pyridine. The application of this method to the syntheses of pyrimidines (ddU, ddT, ddC), 6-substituted purines (ddA, ddI, 6-chloro-ddP, N6-Me-ddA), and 2,6-disubstituted purines (2-F-ddA, 6-chloro-2-amino-ddP) as well as selected 2',3'-didehydro-2',3'-dideoxy derivatives is reported.

  Stereoselectivities in coupling reactions between silylated pyrimidine bases and 3- or 2-alpha-phenylthio-2,3-dideoxyribose were examined. In the former case, no stereoselectivies were observed when the coupling reactions were performed either with 1-chlorosugar in an S(N)2 mode or in the presence of Lewis acids as catalyst in an S(N)1 mode. Coupling reaction with 2-alpha-phenylthio-2,3-dideoxyribose in the presence of Lewis acids, especially SnCl4, proceeded with good stereoselectivity to give anomeric mixtures of alpha:beta = 1:9. All these nucleosides were converted to 2',3'-didehydro-2',3'-dideoxynucleosides by oxidation to sulfoxides followed by thermal elimination of sulfenic acid.
