  • p-Methoxybenzyl-N-phenyl-2,2,2-trifluoroacetimidate: a versatile reagent for mild acid catalyzed etherification
    作者:Nadine Barroca-Aubry、Mohamed Benchekroun、Filipe Gomes、David Bonnaffé
    DOI:10.1016/j.tetlet.2013.07.066
    日期:2013.9
    PMB-NPTFA la is a new month bench stable and powerful reagent for the formation of PMB ethers. Several alcohols were protected in high yields and short reaction times, using low reagent loading and small catalytic amounts of Bi(OTf)(3). The mild conditions of the reaction confer a good orthogonality to acid- and base-sensitive protecting groups. (C) 2013 Elsevier Ltd. All rights reserved.
  • Repairing the Thiol-Ene Coupling Reaction

    AbstractThiol‐ene coupling (TEC) reactions emerged as one of the most useful processes for coupling different molecular units under reaction mild conditions. However, TEC reactions involving weak CH bonds (allylic and benzylic fragments) are difficult to run and often low yielding. Mechanistic studies demonstrate that hydrogen‐atom transfer processes at allylic and benzylic positions are responsible for the lack of efficiency of the radical‐chain process. These competing reactions cannot be prevented, but reported herein is a method to repair the chain process by running the reaction in the presence of triethylborane and catechol. Under these reaction conditions, a unique repair mechanism leads to an efficient chain reaction, which is demonstrated with a broad range of anomeric O‐allyl sugar derivatives including mono‐, di‐, and tetrasaccharides bearing various functionalities and protecting groups.

    described. The L-iduronyl and D-glucuronyl disaccharides 1−3 were then prepared from these compounds, by means of efficient and regioselective protective group manipulations. These disaccharides form the basis of a combinatorial approach toward the synthesis of heparan sulfate fragments representative of the heterogeneous regions of this polysaccharide.

    due to the presence of the N-acetyl group, which inhibits the trichloroacetimidate-mediated glycosylation, since the analogous reaction proceeds smoothly once the N-acetyl group has been replaced by an azide. In the latter case, we show that the careful optimisation of the solvent system is a powerful way to obtain high yields and α-stereoselectivity in coupling reactions of 1 with the 4-OH of a GlcUA
    为了制备还原端含有 N-乙酰化葡糖胺的生物学相关硫酸乙酰肝素 (HS) 四糖片段,我们研究了 2-叠氮葡萄糖三氯乙酰亚胺二糖供体 1 与一系列 4'-OH-糖醛酸二糖受体之间的糖基化反应在还原末端带有 N-乙酰氨基葡萄糖。虽然我们尝试了几种缩合条件,但没有形成四糖。我们表明这些反应的失败是由于 N-乙酰基的存在,它抑制了三氯乙酰亚胺介导的糖基化,因为一旦 N-乙酰基被叠氮化物取代,类似的反应就会顺利进行。在后一种情况下,我们表明,仔细优化溶剂系统是在 1 与 GlcUA 受体的 4-OH 偶联反应中获得高产率和 α-立体选择性的有效方法。因此,在 THF/Et2O (9:1) 系统中,我们获得了 GlcUA-β-(1→4)-GlcN3-α-(1→4)-GlcUA-β-(1→4)-GlcN3 四糖 16α /β 的分离产率为 90%,α/β 比为 92:8,而使用 CH2Cl2 时的产率为 57%,α/β
