  • Synthetic routes to methyl 3-deoxy-aldulosonic acid methyl esters and their 2-deoxy isomers based on the Horner-Emmons and Peterson reaction of sugar lactones
    作者:Jacek Młynarski、Anna Banaszek

    The two reagents: 2-trimethylsilyl- and 2-[bis(2,2,2-trifluoroethoxy)phosphoryl]-1,3-dithianes were engaged in the construction of appropriate ketene thioacetals from the isomeric 2-deoxy-hexono-1,5-lactones via Horner-Emmons or Peterson reaction. A comparison of the results shows that the second reagent is more promising, as it forms the desired ketene thioacetals as sole products. The latter were

    EBC‐23, 24, 25, 72, 73, 75 and 76 were isolated from the fruit of Cinnamomum laubatii (family Lauraceae) in the Australian tropical rainforests. EBC‐23 (1) was synthesized stereoselectively, in nine linear steps in 8 % overall yield, to confirm the reported relative stereochemistry and determine the absolute stereochemistry. Key to the total synthesis was a series of Tietze–Smith linchpin reactions

    intermediates for the synthesis of carbohydrates. The addition of the triphenyl phosphite ligand shuts down the isomerization pathway and promotes the allylic etherification pathway. The addition of diphenyl phosphate improved the diastereoselectivity for the addition reaction. Interestingly, opposite diastereoselectivity was observed for sterically demanding alcohol nucleophiles compared to less sterically
    我们最近为Achmatowicz重排产物开发了一种新型的Ir催化的动态动力学异构化反应。在此更新中,我们表明,在适当的配体和添加剂存在下,源自Achmatowicz重排的产物也可以进行Ir催化的动态动力学烯丙基醚化反应,从而提供用于合成碳水化合物的有用中间体。亚磷酸三苯酯配体的添加关闭了异构化途径并促进了烯丙基醚化途径。磷酸二苯酯的加入改善了加成反应的非对映选择性。有趣的是,与对空间要求较低的醇亲核试剂相比,对空间要求较高的醇亲核试剂观察到相反的非对映选择性。该方法还适用于几种2的合成

    Sharpless catalytic asymmetric dihydroxylation to vinylfuran. The resulting diols are produced in high enantioexcess and can be stereoselectively transformed into α,β-unsaturated-δ-lactones via a short highly diastereoselective oxidation and reduction sequence. Wittig olefination or Julia olefination reactions were used to introduce the phenyl group side chain either cis or trans selectively and these
    到高度官能化的α,β不饱和δ内酯的柔性对映选择性途径,已经允许用于styryllactones的合成:altholactone,isoaltholactone,3-外延-altholactone,2-外延-altholactone和5-羟基goniothalamin在2.5,10,糠醛的总收率分别为5%,1%和13%。通过将Sharpless催化不对称二羟基化反应应用于乙烯基呋喃,此方法可得出其不对称性。所产生的二醇以高对映体过量产生,并且可以通过短的高度非对映选择性氧化和还原序列立体选择性地转化为α,β-不饱和-δ-内酯。使用维蒂希(Wittig)烯化或朱莉娅(Julia)烯化反应来引入顺式或反式的苯基侧链 选择性地将这些中间体通过选择性环氧化反应进一步精制为内酯异构体。
  • Syntheses of four d- and l-hexoses via diastereoselective and enantioselective dihydroxylation reactions
    作者:Joel M. Harris、Mark D. Keränen、Hang Nguyen、Victor G. Young、George A. O'Doherty
    DOI:10.1016/s0008-6215(00)00031-8
    日期:2000.8
    An expeditious approach to various protected hexoses has been developed by the use of the Sharpless catalytic asymmetric dihydroxylation reaction. Applying the Sharpless catalytic asymmetric dihydroxylation reaction on vinylfuran, diols with high enantioexcess are produced. The resulting diols call be stereoselectively transformed into either protected D- or L-mannose in five steps and approximately 39% yield from furfural. Similarly, both D- and L-talose and gulose have been synthesized in 19% overall yields, respectively. Using a modified strategy, both protected D- and L-gulo- and allo-sugar-delta-lactones were synthesized in eight steps and similar to 20% overall yield from furfural. (C) 2000 Elsevier Science Ltd.
