  • An Oxazaphospholidine Approach for the Stereocontrolled Synthesis of Oligonucleoside Phosphorothioates
    作者:Natsuhisa Oka、Takeshi Wada、Kazuhiko Saigo

    日期:2003.7.1
    diastereoselectivity. After sulfurization and deprotection, diastereopure (R(p))- and (S(p))-dinucleoside phosphorothioates were obtained in excellent yields. The present methodology was also applied to the solid-phase synthesis of stereoregulated PS-ODNs. all-(R(p))-[T(PS)](3)T, all-(S(p))-[T(PS)](3)T, all-(R(p))-d[G(PS)A(PS)C(PS)]T, and all-(R(p))-[T(PS)](9)T were synthesized on a highly cross-linked polystyrene resin
    描述了使用核苷 3'-O-oxazaphospholidine 衍生物作为单体单元的低聚脱氧核糖核苷硫代磷酸酯 (PS-ODNs) 的立体控制合成。2-Chloro-1,3,2-oxazaphospholidine 衍生物由六种对映纯的 1,2-氨基醇制备而成,用于 5'-O-保护核苷的磷酸化反应。对这些反应的详细研究表明,该反应的非对映选择性取决于对映体纯 1,2-氨基醇的结构、反应温度和用作 HCl 清除剂的胺。此外,还对 2-氯氧氮杂磷脂衍生物进行了从头算分子轨道计算,以阐明这些非对映选择性磷酸化反应的机理。发现磷原子上的 2-氯-5-苯基氧氮杂磷脂衍生物的 LUMO 几乎与 P-Cl 键正交。该 LUMO 可能参与主要保留 P 构型的磷酸化反应。开发了一系列二烷基(氰甲基)铵盐,并将其用作非对映纯核苷 3'-O-oxazaphospholidines 与 3'-O-保护的核苷的缩合
  • Diastereocontrolled Synthesis of Dinucleoside Phosphorothioates Using a Novel Class of Activators, Dialkyl(cyanomethyl)ammonium Tetrafluoroborates

    A novel class of activators, dialkyl(cyanomethyl)ammonium tetrafluoroborates 1a-c, has been developed and applied to the condensations of diastereopure 5'-O-tert-butyldiphenylsilylthymidine 3'-cyclic phosphoramidites 3a-d with 3'-O-tert-butyldimethylsilylthymidine (4a). Among them, the condensation of 3a with 4a in the presence of 1a completed within 5 min and gave only one diastereoisomer of the corresponding

  • Stereoselective synthesis of dinucleoside boranophosphates by an oxazaphospholidine method
    作者:Takeshi Wada、Yukihiro Maizuru、Mamoru Shimizu、Natsuhisa Oka、Kazuhiko Saigo
    DOI:10.1016/j.bmcl.2006.03.076
    日期:2006.6
    A stereoselective synthesis of dinucleoside boranophosphates by using nucleoside 3'-oxazaphospholidine derivatives is described. The diastereoselectivity of the internucleotidic bond formation reactions varied with the nucleobase used. (Rp)- and (Sp)-dithymidine boranophosphates were synthesized with excellent diastereoselectivity both in solution and on a solid-support, whereas a loss of diastereopurity was observed for the 2'-deoxycytidine derivative having an unprotected nucleobase amino group. On the other hand, complete chemoselectivity of the 3'-oxazaphospholidine derivatives toward hydroxy groups over amino groups was serendipitously found during the study. This unique chemo selectivity of the 3'-oxazaphospholidine derivatives was investigated by comparing them with the conventional nucleoside 3'-phosphoramidite. (c) 2006 Elsevier Ltd.
