  Applications of Cyclic Sulfates of vic-Diols:  Synthesis of Episulfides, Olefins, and Thio Sugars

  摘要：

  A new efficient and expeditious one-pot synthesis of thiiranes and olefins from cyclic sulfates of vic-diols is described. Opening of cyclic sulfates with potassium thioacetate or potassium thiocyanate followed by treatment with sodium methoxide led to episulfides. Olefins were obtained when potassium selenocyanate was used as nucleophile, and the obtained monoesters were treated with sodium borohydride. This method was applied to acyclic polyols derived from chiral glycerine, 1,2-isopropylidenehexofuranoses with different subtituents at C-3, and dimethyl acetals derived from pentoses and hexoses. The methodology is highly versatile, and its applicability has been demonstrated by the synthesis of different 4- and 5-thiosugars by opening of the thiirane ring with sodium acetate or lithium aluminum hydride. Reduction with lithium aluminum hydride of the thiocyanate sulfate potassium salt obtained by the opening of cyclic sulfate with KSCN allowed the direct synthesis of 5-deoxy-4-thio- and 6-deoxy-5-thiosugars. Cyclic thiosugars with the sulfur atom in the ring are obtained by acidic hydrolysis of the 5-thiol derivatives of 1,2-O-isopropylidenehexofuranoses and 4-thiopentose dimethyl acetals. Using this method, an efficient synthesis of 5-thio-L-fucose as well as the synthesis of 2,5-dideoxy-4-thiofuranose is described.

  Cyclic sulfates 21–23 and sulfite 27 derived from glucofuranose lead to the 3,6-anhydrosugar 28 in excellent yields when treated with sodium sulfite or in basic media. When treated with sodium sulfite, the 3-deoxy derivative 24 fails to give the intramolecular cyclization which leads to the anhydrosugars. Instead it gives the disulfonate derivative 26. 28 was used as starting material to prepare bicyclonucleosides

  当用亚硫酸钠或在碱性介质中处理时，衍生自葡糖呋喃糖的环状硫酸盐21 – 23和亚硫酸盐27以极高的产率生成3,6-脱水糖28。当用亚硫酸钠处理时，3-脱氧衍生物24不能产生分子内环化作用，从而导致脱水糖。相反，它给出二磺酸盐衍生物26。使用28作为起始原料制备双环核苷43和46，它们是抗HIV药物ddC和ddA的类似物。
