  • Iodine: A versatile reagent in carbohydrate chemistry IV. Per-O-acetylation, regioselective acylation and acetolysis
    作者:K.P.Ravindranathan Kartha、Robert A. Field
    DOI:10.1016/s0040-4020(97)00742-4
    日期:1997.8
    acid for promoting the per-O-acetylation of unprotected sugars. Under controlled conditions it can bring about regioselective acylation of carbohydrate derivatives. At higher concentration and with longer reaction times, iodine can effect the selective acetolysis of benzyl ether-protected primary hydroxyl groups. All of these reactions proceed in high yield, are easy to carry out and make use of readily
    已经发现碘是用于促进未保护的糖的过-O-乙酰化的有效的路易斯酸。在受控条件下,它可以引起碳水化合物衍生物的区域选择性酰化。在更高的浓度和更长的反应时间下,碘会影响苄基醚保护的伯羟基的选择性乙酰水解。所有这些反应均以高收率进行,易于进行,并利用廉价且易于处理的碘。
  • Extending the possibility of an N-Troc-protected sialic acid donor toward variant sialo-glycoside synthesis
    作者:Hiromune Ando、Yusuke Koike、Hideharu Ishida、Makoto Kiso
    DOI:10.1016/s0040-4039(03)01707-6
    日期:2003.9
    The potential of an N-Troc-protected sialic acid donor, equipped with phenylsulfenyl functionality as a leaving group, has been explored. As a result, the entitled donor was proven to be highly reactive and to have broad applicability toward the synthesis of variant sialo-glycans, which have N-glycolyl, de-N-acetyl, 1,5-lactam and 8-O-sulfo sialic acid analogs.
    已经研究了具有苯基亚磺酰基官能团作为离去基团的N -Troc保护的唾液酸供体的潜力。结果,证明了有资格的供体是高反应性的,并且对于合成具有N-羟甲基,脱-N-乙酰基,1,5-内酰胺和8- O-磺基的唾液聚糖的变体具有广泛的适用性。唾液酸类似物。
  • A novel and versatile glycosyl donor for the preparation of glycosides of N-acetylneuraminic acid
    作者:Alexei V Demchenko、Geert-Jan Boons
    DOI:10.1016/s0040-4039(98)00359-1
    日期:1998.5
    An N-diacetyl derivative of neuraminic acid exhibits excellent glycosyl donor properties and is a very useful substrate for the preparation of glycosides of N-acetylneuraminic acid. The donor will be a key component in the preparation of a heptasaccharide derived from group B type III Streptococcus.

    phenylthio. Compound 8 was converted into the methyl beta-thioglycoside via O-benzoylation, replacement of the 2-(trimethylsilyl)ethyl group by acetyl, and introduction of the methylthio group by reaction with methylthiotrimethylsilane. Compound 17 was converted, via O-acetylation, selective removal of the 2-(trimethylsilyl)ethyl group, and reaction with trichloroacetonitrile, into the alpha-trichloroacetimidate

  • Thiomidoyl approach to the synthesis of α-sialosides
    作者:Cristina De Meo、Olivia Parker
    DOI:10.1016/j.tetasy.2004.11.043
    日期:2005.1
    Novel sialosyl donors, S-benzoxazolyl (SBox) and S-thiazolyl (STaz) sialosides, have been synthesized and applied to the stereoselective synthesis of alpha-sialosides. It was also demonstrated that it is possible to selectively activate SBox sialyl donor over ethyl thioglycoside, allowing the direct synthesis of disaccharide donors that could be used in subsequent glycosylations without further manipulations.
