  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.

• Introduction of an alkyl group into the sugar portion of uracilnucleosides by the use of Gilman reagents.

  Substitution of a p-toluenesulfonyloxy group in the sugar portion of uracilnucleosides by an alkyl group was investigated by using Gilman reagents (R2CuLi). In the cases of 5'-O-tosyl derivatives of 2', 3'-O-isopropylideneuridine, moderate vields of 5'-alkylated products were obtained. In contrast to this, the reactions of the corresponding 2'-deoxyuridine derivatives gave higher yields of products. A similar substitution reaction at the 3'-position of 2'-deoxyuridine derivatives was also examined.

  用Gilman试剂（R2CuLi）研究了尿嘧啶核苷糖部分的p-甲苯磺酰氧基被烷基取代的反应。对于2',3'-O-异亚丙基尿苷的5'-O-甲苯磺酸衍生物，得到了中等收率的5'-烷基化产物。与此相反，相应的2'-脱氧尿苷衍生物的反应则得到了更高收率的产物。还考察了在2'-脱氧尿苷衍生物的3'位进行类似取代反应的情况。

  A series of 2-(2-oxoalkylidene)-4(1H)-pyrimidinone nucleoside analogs were synthesized by the addition of the lithium enolates of methylketones to 2,5′- and 2,2′-anhydrouridines and to 2,5′-anhydrothymidines. Alternatively, 2-thiouridine was alkylated with bromomethyl ketones to yield 2-(2-oxoalkyl)thio-4(1H)-pyrimidinone ribofuranosides in good yields. These intermediates were subsequently transformed
