  • 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
    合成了四种新的单氮杂15冠5型基于核糖-己吡喃糖苷的手性套索状醚和两种基于阿拉托吡喃糖苷的冠状醚。我们的合成通过亲核试剂利用了2,3-脱水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-脱水-4,6-O-亚苄基-α-D-甘露吡喃糖苷与乙醇胺的反应特别令人感兴趣,以提供3-取代的萘并吡喃糖苷。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-六吡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-脱氧己-5-烯吡喃苷衍生物是通过将6-溴-6-脱氧或6-O-对甲苯磺酰己吡喃苷与碘离子及1,8-二氮杂双环[5.4.0]十一烯在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-无水吡喃苷衍生物外,其他的反应产物(如altropyranoside和2-脱氧核糖己吡喃苷衍生物)产率较高。甲基分支的6-脱氧己-5-烯吡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-苄叉基吡喃糖苷衍生物在溴代三氯甲烷中进行光溴化后,会生成溴-脱氧-吡喃侧苯甲酸苯甲酸酯和立体异构体,对于2,3-和3的酰基衍生物,4-缩醛优于它们与N-溴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.
    脱氧糖衍生物由相应的三酸酯、对甲苯磺酸盐、卤素和环氧化物衍生物制备而成。利用四丁基四氢硼酸铵试剂,脱氧反应通过 SN2 型置换进行,收率很高。
