  • Total Synthesis of 3-Deoxy-<scp>d</scp>-<i>manno</i>-2-octulosonic Acid (KDO) and 2-Deoxy-β-KDO
    作者:Steven D. Burke、Geoffrey M. Sametz
    DOI:10.1021/ol9905506
    日期:1999.7.1
    [formula: see text] Total syntheses of KDO and 2-deoxy-beta-KDO are reported. The C2-symmetric dienediol 4 was desymmetrized by conversion to its corresponding 1,4-dioxanone 5. Ireland-Claisen rearrangement of 5 provided the 6-vinyldihydropyran-2-carboxylate template 6. Double-Sharpless asymmetric dihydroxylation gave the tetraol 7a, which was converted to KDO and 2-deoxy-beta-KDO using methods similar
    [化学式:见正文]报告了KDO和2--β-KDO的总合成。通过转化成其相应的1,4-二恶烷5使C2-对称二二醇4不对称化。5的爱尔兰-克莱森重排提供了6-乙烯基喃-2-羧酸模板6。无双尖锐的不对称二羟基化得到四醇7a,其为转换为KDO和2-deoxy-beta-KDO的方法与以前报道的方法类似。这种合成方案为KDO和KDO类似物提供了灵活的途径。

    synthetic routes to 3-deoxy- d - manno -octulo­sonic acid (KDO) and 3-deoxy- d - arabino -2-heptulosonic acid (DAH) from common sugar substrates are reported. Chain homologation of the sugar substrates was accomplished by Wittig olefination and Corey–Fuchs alkynylation. A new cyclization strategy was investigated to access the desired pyranosyl isomer of the KDO target.

  • An In-Depth Study on Ring-Closing Metathesis of Carbohydrate-Derived α-Alkoxyacrylates:  Efficient Syntheses of DAH, KDO, and 2-Deoxy-β-KDO
    作者:Koen F. W. Hekking、Marcel A. H. Moelands、Floris L. van Delft、Floris P. J. T. Rutjes

    日期:2006.8.1
    Novel, efficient synthetic pathways to DAH, KDO, and 2-deoxy-β-KDO are described. Ring-closing metathesis (RCM) of highly functionalized α-alkoxyacrylate fragments resulted in a series of synthetically versatile oxygen heterocyclic intermediates. Further functionalization of the resulting enol ether double bond and subsequent deprotection provided the natural products in high overall yields, starting
    描述了通往DAH,KDO和2-deoxy-β-KDO的新颖,有效的合成途径。高度官能化的α-烷丙烯酸片段的闭环复分解(RCM)导致了一系列合成上通用的杂环中间体。从可商购的被保护的糖开始,所得醇醚双键的进一步官能化和随后的保护以高的总收率提供了天然产物

    17b , conversion of 17b by deamination to the β-lactone 19 , and nucleophilic opening of the β-lactone ring of 19 with hydroxide and triethyl phosphite, respectively, to give 4b and 4c . An interesting contrast in the reaction with azide of the methyl and the (methylthio)methyl glycosides of the 1- O -alkylsulfonates 9b and 9f , respectively, was observed. Whereas the former reacted by direct displacement
    摘要由Kdo制备了β-端羟基被取代甲基取代的3--d-甘露糖辛酸(Kdo)的类似物。取代的甲基是从Kdo的羧基衍生而来的,而类似物的羧基是通过叠氮乙酸甲酯12d与Me 3 SiCN的立体定向反应引入的,从而得到腈16。16的腈基的解得到叠氮羧酸17a。17a的化得到氨基酸4a。分别制备2-羟甲基和2-膦酰基甲基类似物4b和4c的关键步骤是将叠氮甲基生物17a选择性还原为甲基生物17b,通过基作用将17b转化为β-内19,分别用氢氧化物和亚磷酸三乙酯对19的β-内环进行亲核开环,得到4b和4c。在1-O-烷基磺酸盐9b和9f的甲基和(甲基)甲基糖苷与叠氮化物的反应中观察到有趣的对比。前者通过直接置换反应而得到未重排的叠氮化物9d,而后者通过的参与而发生反应而得到重排的叠氮化物11。

    Allyl glycosides (ketosides) of pyranosidic 3-deoxy-d-manno-2-octulosonic acid (Kdo), phosphorylated at either positions 4 or 5 were synthesized with the aim to study the biological properties of phosphorylated Kdo. The α and β-allyl glycosides prepared from a pyranosidic fluoride of diisopropylidene Kdo were protected at the 7- and 8-positions, and then O-phosphorylated at the 4- or 5-position by the phosphoramidite procedure. Separation of the positional isomers followed by deprotection afforded four compounds in pure states.
