  • Glycosylation of a Ketone with an <i>O</i>-Glycosyl Trichloroacetimidate Provides an Enol Glycoside
    作者:Xianglai Liu、Sumei Ren、Qi Gao、Chun Hu、Yingxia Li、Ning Ding
    DOI:10.1021/acs.orglett.8b02126
    日期:2018.9.7
    An enol-type glycosylation reaction has been investigated. Enol glycosides can be obtained from the reaction between O-glycosyl trichloroacetimidates and the corresponding ketones promoted by an acid. The enol glycosides derived from cyclic ketones can be afforded efficiently and isolated in good yield, while those from acyclic ketones are prepared in low conversion or are too labile for isolation
    已经研究了烯醇型糖基化反应。烯醇糖苷可以从O-糖基三氯乙亚氨酸酯与相应的由酸促进的酮之间的反应中获得。可以有效地提供衍生自环状酮的烯醇糖苷并以高收率分离,而衍生自无环酮的烯醇糖苷转化率低或太不稳定而无法分离。对不同糖基供体类型的进一步研究表明,只有O-糖基三氯乙酰亚氨酸酯可以很好地用作烯醇糖基化的供体。

    O-glycosylation of primary alcohols with O-protected thioglycosides was performed in the presence of a small amount of sodium trifluoromethansulfonate (12.5 mol % to glycosyl acceptor) as a supporting electrolyte. The reaction was successfully carried out in an undivided cell to give O-glycosides in good yields with a high electro-efficiency (ca. 1 F/mol) at 15 °C in acetonitrile.

  • Synthesis of glycosyl fluorides from thio-, seleno-, and telluroglycosides and glycosyl sulfoxides using aminodifluorosulfinium tetrafluoroborates
    作者:Sammi Tsegay、Rohan J. Williams、Spencer J. Williams
    DOI:10.1016/j.carres.2012.04.016
    日期:2012.8
    Glycosyl fluorides can be synthesized from thio-, seleno-, and telluroglycosides and glycosyl sulfoxides using the aminodifluorosulfinium tetrafluoroborate reagents Xtalfluor-E and -M, with or without added N-bromosuccinimide. Mechanistic studies provide evidence that fluoride is delivered from the tetrafluoroborate counterion. (C) 2012 Elsevier Ltd. All rights reserved.

    The synthesis of N alpha-fluorenylmethoxycarbonyl-trans-4-hydroxy-4-O[(2,3,4,6-tetra-O-acetyl)-alpha-D-mannopyranosyl]-L-proline allyl ester and N alpha-fluorenylmethoxycarbonyl- trans-4-hydroxy-4- O-[(2,3,4,6-tetra- O-benzoyl) -alpha-D -mannopyranosyl]-L -proline allyl ester is described. Glycosylation using Konigs-Knorr conditions with a benzoyl protected glycosyl donor provided the optimum method. Removal of the allyl ester gave two mannosylated building blocks suitable for solid phase glycopeptide synthesis. (c) 2007 Elsevier Ltd. All rights reserved.
