    Stereocontrolled Photocyclization of 1,2-Diketones: Application of a 1,3-Acetyl Group Transfer Methodology to Carbohydrates
    摘要:
    Photolysis of 1-glycosyl-2,3-butanodione derivatives using visible light is a mild and selective procedure for the synthesis of chiral 1-hydroxy-1-methyl-5-oxaspiro[3.5]nonan-2-one carbohydrate derivatives. The results strongly suggest that stereocontrol of the cyclization is dependent on conformational and stereoelectronic factors. Further oxidative opening, of the 1-hydroxy-1-methyl-2-cyclobutanone moiety affords new C-ketoside derivatives either in C- and O-glycoside series. This tandem two-step process could be considered to be a stereocontrolled 1,3-transference of an acetyl group, and it can be applied either to pyranose and furanose models.

    In the presence of a catalytic amount of trityl perchlorate, 1-O-acetyl ribose stereoselectively reacts with silylated nucleophiles, such as silyl enol ether, allylsilane, and trimethylsilyl cyanide, to give the corresponding α-C-ribofuranosides in excellent yields.

    anomer to give a mixture. The C-allylation reaction gave only the α- d anomer. C-Pentanonylation, however, gave a mixture of diastereoisomers that could not be isolated. All reactions afforded almost the same results starting with either α- or β- d -ribofuranosyl fluoride. No reaction of the β anomer of 5 with 1-isopropyl-2-methyl-1-propenyl trimethylsilyl ether took place.

    作者:Hai Thanh Dao、Uwe Schneider、Shū Kobayashi
    DOI:10.1002/asia.201100096
    日期:2011.9.5
    our work highlights for the first time the correlation between the Lewis acidity of “electrophilic” boron‐based compounds and their “nucleophilic” reactivity in Csp3–Csp3 couplings, catalyzed by a “soft” low‐oxidation main group metal. In addition, we also report several applications of these methodologies to the selective synthesis of various carbohydrate derivatives.
    我们最近发现了一种通用的铟(I)催化方法,可与水和空气稳定的烯丙基硼酸酯进行缩醛和缩酮的烯丙基化和炔丙基化。通过使用更具反应性的烯丙基硼烷,我们已成功地将此方法扩展至更具挑战性的CC与醚偶联。本文中,我们报告了一种改进的方法,该方法是通过将烯丙基硼酸酯与市售的“硬”路易斯酸B-甲氧基-9-BBN(BBN = borabicyclo [3.3] .1]壬烷),作为有效的助催化剂。重要的是,我们的工作首次强调了“亲电子”硼基化合物的路易斯酸度与它们在Csp 3 –Csp中的“亲核”反应性之间的相关性。3种偶合,由“软”低氧化主族金属催化。此外,我们还报告了这些方法在多种碳水化合物衍生物的选择性合成中的几种应用。
  • Synthesis of C-5-thioglycopyranosides and their sulfonium derivatives from 1-C-(2′-oxoalkyl)-5-S-acetylglycofuranosides
    作者:Tian Yi、Shih-Hsiung Wu、Wei Zou
    DOI:10.1016/j.carres.2004.11.014
    日期:2005.2
    D-xylose were converted to 1-C-(2'-oxoalkyl)-5-thioglycopyranosides by base treatment. The transformation was achieved through beta-elimination to an acyclic alpha,beta-conjugated aldehyde (ketone or ester), followed by an intramolecular hetero-Michael addition by the 5-thiol group. The cycloaddition was highly stereoselective in favor of an equatorial 1-C-substitution. The resultant C-5-thioglycopyranosides
    通过碱处理将L-阿拉伯糖,D-核糖和D-木糖的1-C-(2'-氧代烷基)-5-S-乙酰基呋喃糖苷转化为1-C-(2'-氧代烷基)-5-硫代吡喃果糖苷。通过β-消除成无环α,β-共轭醛(酮或酯),然后通过5-硫醇基团进行分子内杂-迈克尔加成,实现了转化。环加成是高度立体选择性的,有利于赤道1-C取代。通过用环状硫酸盐和甲基碘处理,将所得的C-5-硫代糖吡喃果糖苷进一步转化为the盐。由于存在S-轴和S-赤道取代基,获得了两种sulf异构体。
