    Deoxygenation/dimerization of sugar derivatives with BF3·Et2O–Et3SiH: synthesis of a β-isonucleoside
    摘要:
    Lewis acid-Et3SiH induced deoxygenation of anomeric carbon of sugars generates tetrahydrofuran derivatives, accompanied by hitherto unknown dimeric products. If the reagent addition steps are reversed, tetrahydrofuran derivatives are obtained as the sole products, while only the dimeric products are isolated if Et3SiH is excluded. One of the deoxygenated products has been transformed into a beta-isonucleoside. (C) 2012 Elsevier Ltd. All rights reserved.

  • Allyloxy and Propargyloxy Group Migration: Role of Remote Group Participation in the Synthesis of 5-C-Nucleosides and Other Sugar Derivatives
    作者:Subhrangshu Mukherjee、Prabhash N. Tripathi、Sukhendu B. Mandal
    DOI:10.1021/ol301851q
    日期:2012.8.17
    In 1-deoxy-xylofuranose derivatives possessing a good leaving group at 2-C, participation of allyloxy and propargyloxy substituents at 5-C results in loss of the 2-C substituent and attack of various nucleophiles at 5-C of the oxonium intermediate. Such participation of a benzyloxy or crotyloxy group leads to dioxabicyclo[2.2.1]heptane rings.
    在2-C处具有良好离去基团的1-脱氧-木呋喃糖衍生物中,烯丙基氧基和炔丙基氧基取代基在5-C处的参与导致2-C取代基的丢失和各种亲核试剂在氧中间体的5-C处的进攻。苄氧基或巴豆氧基的这种参与导致二氧杂双环[2.2.1]庚烷环。

    and 26a,b) and glucofuranoside (3a, 7a, 8a,b) ligands with C1 symmetry have been prepared and used in the Rh-catalyzed asymmetric hydroformylation of styrene. The main structural features of these ligands are a) the presence of a 6-O-isopropyl group in ligands with a gluco configuration, b) the absence of 1,2-O-isopropylidene, a common group in many ligands with a furanoside skeleton, c) the presence

  • New metal-free one-pot synthesis of α-2-deoxy-Ulosides by microwave-assisted double Michael Addition of β-enamino ketones
    作者:Pin-Chun Lin、Zi-Ping Lin、Po-Yen Chen、Min-Tsang Hsieh、Hui-Chang Lin

    New metal-free one-pot synthesis of α-2-deoxy-ulosides in moderate to good yields by microwave-assisted double Michael addition of various O-nucleophiles to β-enamino ketones in the presence of 12 N HCl. These glycosyl additions occurred with high α-stereoselectivity and were complete in 10–25 min in 51–93% yield. In addition, high α-stereoselectivity was also observed when S-nucleophiles were examined
    在 12  N HCl存在下,通过微波辅助将各种O-亲核试剂双迈克尔加成到 β-烯胺酮中,以中等到良好的收率实现 α-2-脱氧-uloside 的新型无金属一锅法合成。这些糖基添加具有高 α-立体选择性,并在 10-25 分钟内完成,产率为 51-93%。此外,当检查S-亲核试剂时,也观察到高 α-立体选择性。

    日期:2004.3
    A simple and efficient method for the preparation of isonucleoside 7 is described. The preparation of 1,4-anhydroxylitol 4, a key intermediate, is described by intramolecular cyclization of (2S,3R,4R)-3,5-dibenzyloxypentan-1,2,4-triol 3 using diethyl carbonate and NaH.

  • An Efficient One-Stage Deprotection/Reduction of 1,2-<i>O</i>-Isopropylidene Furanoses to the Corresponding Tetrahydrofurans
    作者:Gregory J. Ewing、Morris J. Robins
    DOI:10.1021/ol9901117
    日期:1999.8.1
    Treatment of 1,2-O-isopropylidenefuranose derivatives with triethylsilane/boron trifluoride etherate results in generation of the corresponding tetrahydrofurans. This one stage process removes the 1,2 O-isopropylidene group with accompanying deoxygenation at the anomeric position and is compatible with several hydroxyl protecting groups.
