  • Synthesis of hydroxymethyl branched [3.2.0]bicyclic nucleosides using a regioselective oxetane ring-formation
    作者:Nanna K. Christensen、Ann Katrine L. Andersen、Trine R. Schultz、Poul Nielsen

    ring-formation to give after deprotection the bicyclic nucleoside 34. The surprisingly efficient formation of an oxetane was first discovered by serendipity on a corresponding methylfuranoside derivative. The allo-configured bicyclic nucleoside 34 was easily shortened to a ribo-configured analogue 35 by a diol-cleaving reaction and subsequent reduction. Both 34 and 35 are conformationally restricted in the important
    已经有效地合成了分别具有一个和两个羟甲基取代基的两个[3.2.0]双环核苷35和34。由双丙酮-D-葡萄糖容易地制备受保护的(3'-C-乙烯基-β-D-烷基呋喃糖基)胸腺嘧啶衍生物28,并且胸腺嘧啶部分被BOM-基团保护。在2'-位引入离去基团后,随后的核苷31用作立体选择性二羟基化和区域选择性氧杂环丁烷环形成的底物,以在脱保护后得到双环核苷34。令人惊奇地有效形成氧杂环丁烷偶然发现了相应的甲基呋喃糖苷衍生物。通过二醇裂解反应和随后的还原,容易将异构型双环核苷34缩短为核糖构型的类似物35。
  • Synthesis of bicyclic nucleosides by ring-closing metathesis
    作者:Jacob Ravn、Poul Nielsen
    DOI:10.1039/b101364p
    日期:——
    The ring-closing metathesis method is applied in the construction of conformationally restricted bicyclic nucleosides. From diacetone-D-glucose, the unsaturated bicyclic carbohydrate derivative 11 is efficiently obtained through two vinyl group Grignard additions, subsequent metathesis of the double bonds, and resolution of the stereochemistry by an oxidation/reduction reaction sequence. Two separate routes differing in the 3-O-protecting group are compared. Thus, an additional protecting step improves the yields significantly. Standard conversions of 11 give the bicyclic nucleoside 22 containing an olefinic moiety with a high potential for further functionalisation. As examples, two simple bicyclic ribo-nucleoside analogues 4 and 5, which are restricted to the unusual South-type conformations, are synthesised.
    环闭合转位法用于构建构象受限的双环核苷。从二乙酮-D-葡萄糖出发,经过两次烯基格林纳反应、后续双键的转位以及通过氧化/还原反应序列解决立体化学,成功合成了不饱和双环糖类衍生物11。比较了两条在3-O-保护基团上不同的合成路线。因此,额外的保护步骤显著提高了产率。将11进行标准转化,得到含有具有较高进一步功能化潜力的烯基部分的双环核苷22。作为示例,合成了两种简单的双环核糖核苷类似物4和5,这些类似物限制在不寻常的南型构象中。
  • Strategies and tactics for free radical carbocyclization: synthesis of polyfunctionalized cyclopentanoid molecules from carbohydrates
    作者:José Marco-Contelles、Pilar Ruiz、Luis Martínez、Angeles Martínez-Grau
    DOI:10.1016/s0040-4020(01)81837-8
    日期:1993.7
    The tributyltin hydride + azobisisobutyronitrile (AIBN) mediated free radical carbocyclization of precursors 1-9, 48 and 49 is described. The resulting carbocycles have been obtained in moderate yield and good diastereoselectivity. These polyfunctionalized, enantiomerically pure cyclopentane derivatives are useful intermediates for further manipulation.

    steps from diacetone-D-glucose, taking advantage of a stereoselective Grignard reaction, a stereoselective dihydroxylation and a regioselective tandem ring-closing procedure. The configuration of 3 is confirmed by measuring the 3JHH coupling constants in connection with molecular modelling and ab initio calculations, as these exclude alternative tricyclic nucleoside structures.

  • SYNTHESIS AND NMR-ANALYSIS OF TRICYCLIC NUCLEOSIDES
    作者:Poul Nielsen、Michael Petersen、Jens Peter Jacobsen
    DOI:10.1081/ncn-100002543
    日期:2001.3.31
    Two anomeric tricyclic nucleosides have been synthesised from diacetone-D-glucose using oxidation, stereoselective Grignard-addition of a vinyl-group, a stereoselective dihydroxylation followed by a tandem ring closing reaction, and finally a nucleobase coupling. The main beta -configured product was examined and its configuration confirmed using NMR-spectroscopy in connection to ab initio calculations. The preferred conformation of this tricyclic nucleoside was described.
