  Stereoselectivity in the Coupling Reaction between 2-Phenylthio-2,3-dideoxyribose and Silylated Pyrimidine Bases

  摘要：

  在SnCl4存在下，2-α-苯硫基-2,3-双脱氧核糖与硅化嘧啶碱基的耦合反应以立体选择性方式进行，得到β-异构体。这些核苷随后通过氧化后进行热消除，转化为2′,3′-双脱氧-2′,3′-双脱氢核苷。

  The methodology described herein examines the regio- and stereoselectivity of pyrimidine and purine glycosylations of furanoid glycals. The results show that following stereoselective sulfenylation, glycosylation of furanoid glycals, in the presence of SnCl4, Proceeds both regio- and stereoselectively.

  Furanoid glycal was utilized as a starting material for the nucleoside derivatives with the aid of benzenesulfenyl chloride. Condensation reaction with silylated nucleic bases was high in the presence of SnCl4. Electrophilic addition of benzenesulfenyl chloride to the glycal with substituent also proceeded in high stereoselectivity. Phenylthio-substituted nucleoside was used to convert 2',3'-dideoxynucleoside and 2',3'-didehydro-2',3'-dideoxynucleoside.

  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.
