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

  Coupling reaction between 2-α-phenylthio-2,3-dideoxyribose and silylated pyrimidine bases in the presence of SnCl4 proceeded stereoselectively to give the β-anomers. These nucleosides were converted to 2′,3′-dideoxy-2′,3′-didehydronucleosides by oxidation followed by thermal elimination.

  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。

  A process for producing a nucleoside derivative (1) by reacting a substituted 2,3-dihydrofuran derivative (2) with an organohalogen compound (3) containing a group 16 element of the periodic table to give a substituted 2- halotetrahydrofuran derivative (4), condensing the derivative (4) with a nucleic acid base to give a substituted nucleoside derivative (5), and reducing the derivative (5), wherein R1 represents hydrogen, alkyl or R6-O-CH2-; R2 to R4 represent each hydrogen or a group containing a group 14-17 element of the periodic table; R5 represents optionally substituted alkyl or phenyl; A represents a group 16 element of the periodic table; B represents a nucleic acid base; and X represents halogen.

  通过将取代的2,3-二氢呋喃衍生物（2）与含周期表第16族元素的有机卤化物（3）反应，从而得到取代的2-卤代四氢呋喃衍生物（4），将衍生物（4）与核酸碱基缩合以得到取代的核苷衍生物（5），并还原衍生物（5），从而生产核苷衍生物（1）的方法，其中R1代表氢、烷基或R6-O-CH2-；R2到R4分别代表氢或含周期表第14-17族元素的基团；R5代表可选择地取代的烷基或苯基；A代表周期表第16族元素；B代表核酸碱基；X代表卤素。

  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.
