  • Synthesis of ribo-hexopyranoside- and altrose-based azacrown ethers and their application in an asymmetric Michael addition
    作者:Zsolt Rapi、Péter Bakó、György Keglevich、Áron Szöllősy、László Drahos、László Hegedűs

    日期:2013.1
    The synthesis of four new ribo-hexopyranoside-based chiral lariat ethers of monoaza-15-crown-5 type and two altropyranoside-based crown ethers were elaborated. Our syntheses utilized the regioselective ring opening of the oxiran moiety of the 2,3-anhydro sugars by nucleophilic reagents to afford the key intermediates. The reaction of methyl-2,3-anhydro-4,6-O-benzylidene-α-D-mannopyranoside with ethanolamine
    合成了四种新的单杂155型基于核糖-己喃糖苷的手性套索状醚和两种基于阿拉托喃糖苷的状醚。我们的合成通过亲核试剂利用了2,3-糖的环氧乙烷部分的区域选择性开环,以提供关键的中间体甲基-2,3--4,6-O-亚苄基-α-D-甘露喃糖苷与乙醇胺的反应特别令人感兴趣,以提供3-取代的喃糖苷。当在相转移催化条件下用作乙酰氨基丙二酸二乙酯向反式-β-硝基苯乙烯的迈克尔加成反应中的催化剂时,一种具有4-甲氧基苯基取代基的基于核糖-六喃糖苷的套索状醚诱导对映选择性为80%。
  • Syntheses of 6-Deoxyhex-5-enopyranosides from 6-Bromo-6-deoxy- or 6-<i>O</i>-<i>p</i>-Tolylsulfonylhexopyranosides by the Use of DBU in DMSO
    作者:Ken-ichi Sato、Noriyuki Kubo、Ritsuko Takada、Shogo Sakuma
    DOI:10.1246/bcsj.66.1156
    日期:1993.4
    Various kinds of nonbranched and methyl-branched 6-deoxyhex-5-enopyranoside derivatives were prepared from 6-bromo-6-deoxy or 6-O-p-tolylsulfonylhexopyranoside in a one-pot procedure by a successive treatment with iodide anion and 1,8-diazabicyclo[5.4.0]undec-7-ene in dimethyl sulfoxide. The scope and limitations of this reaction have become apparent by observing the reactions of 18 substrates. The yields of altropyranoside and 2-deoxyribo-hexopyranoside derivatives were high, except for the 2,3-anhydropyranoside derivative. Methyl-branched 6-deoxyhex-5-enopyranoside derivatives were also obtained in practical yields.
    各种非分支和甲基分支的6-己-5-喃苷衍生物是通过将6--6-或6-O-对甲苯磺酰己喃苷与离子及1,8-二氮杂双环[5.4.0]十一二甲基亚砜中进行连续处理,采用一锅法制备的。通过观察18种底物的反应,这一反应的范围和局限性变得明显。除了2,3-无喃苷衍生物外,其他的反应产物(如altropyranoside和2-脱氧核糖喃苷衍生物)产率较高。甲基分支的6-己-5-喃苷衍生物也以实用的产率获得。
  • Ring opening of 2,3-, 3,4-, and 4,6-O-benzylidene acetals of pyranosides by photobromination with bromotrichloromethane
    作者:Jasbir S. Chana、Peter M. Collins、Farnoosh Farnia、David J. Peacock
    DOI:10.1039/c39880000094
    日期:——
    2,3- 3,4-, and 4,6-O-Benzylidene pyranoside derivatives on photobromination in bromotrichloromethane yield bromo-deoxy-pyranoside benzoates regio- and stereo-specifically which, for the acyl derivatives of the 2,3- and 3,4-acetals, is superior to their reaction with N-bromosuccinimide.
    2,3- 3,4-和4,6- O-苄叉基喃糖苷衍生物代三氯甲烷中进行光化后,会生成--喃侧苯甲酸苯甲酸和立体异构体,对于2,3-和3的酰基衍生物,4-缩醛优于它们与N-代琥珀酰亚胺的反应。
  • An Efficient Deoxysugar Synthesis using Bu<sub>4</sub>NBH<sub>4</sub>via an S<sub>N</sub>2 Reduction
    作者:Ken-ichi Sato、Toshio Hoshi、Yasuhiro Kajihara
    DOI:10.1246/cl.1992.1469
    日期:1992.8
    Deoxysugar derivatives were prepared from the corresponding triflate, tosylate, halogen, and epoxide derivatives. Employing the tetrabutylammonium tetrahydroborate reagent, the deoxygenation proceeds via an SN2 type displacement in good yield.
    糖衍生物由相应的三酸对甲苯磺酸盐、卤素和环氧化物生物制备而成。利用四丁基四硼酸试剂,反应通过 SN2 型置换进行,收率很高。
