  Selenoxide elimination for the synthesis of unsaturated-sugar uracil nucleosides

  摘要：

  Introduction of a phenylseleno group to the sugar portion of uracil nucleosides and selenoxide elimination reactions of the resulting selenium-containing derivatives are described. A phenylselenide anion prepared by reducing (PhSe)2 with LialH4 was found to be highly reactive. By using this selenide as a nucleophile, ring openings of various types of cyclonucleosides and nucleosides having an anhydro structure in the sugar portion were accomplished. The products, which contain a phenylseleno group in the sugar portion, were oxidized with m-CPBA in CH2Cl2, and their susceptibility to the selenoxide elimination and regiochemistry of the reaction was investigated.
