    Compound capable of binding to gamma-interferon (γ-IFN), chosen from the molecules corresponding to formula (I) below: in which X is a divalent spacer group that is sufficiently long to allow the two oligosaccharide fragments A and B to each bind to one of the peptide sequences 125 to 143 of the C-terminal ends of a γ-interferon (γ-IFN) homodimer, n represents an integer from 0 to 10, and for example equal to 0, 1, 2, 3, 4 or 5, and each R independently represents a hydrogen atom, an SO 3 − group or a phosphate group, on the condition that no SO 3 − group is in the 3-position of the glucosamine units of compound (I). The invention also relates to the process for preparing these compounds, to the complexes formed by these compounds and gamma-interferon, and to the medicaments comprising these compounds or complexes.

  • Regioselective Reductive Opening of Benzylidene Acetals with Dichlorophenylborane/Triethylsilane: Previously Unreported Side Reactions and How to Prevent Them

    Arylidene acetals are widely used protecting groups, because of not only the high regioselectivity of their introduction but also the possibility of performing further regioselective reductive opening in the presence of a hydride donor and an acid catalyst. In this context, the Et3SiH/PhBCl2 system presents several advantages: silanes are efficient, environmentally benign, and user-friendly hydride
    亚芳基缩醛是广泛使用的保护基团,不仅因为它们的引入具有高区域选择性,而且在氢化物供体和酸催化剂存在下进行进一步的区域选择性还原开环的可能性。在这种情况下,Et 3 SiH/PhBCl 2系统具有几个优点:硅烷是高效、环境友好和用户友好的氢化物供体,而 PhBCl 2为与所有其他布朗斯台德酸或路易斯酸一起使用的独特区域选择性开辟了道路。硅烷。该系统已被多个研究小组广泛使用,我们已经在 4,6- 和 2,4- O - p的还原开环中展示了其高区域选择性受保护的二糖中的-甲氧基亚苄基部分。令人惊讶的是,由于意外形成了几种副产物,它在含 4,6 - O-亚苄基的底物1和2上的使用导致了不可重现的产率。他们的表征使我们能够识别出不同的缺陷,这些缺陷可能会影响用 Et 3 SiH/PhBCl 2试剂系统还原亚芳基的结果:烯烃硼氢化、叠氮化物还原和/或路易斯酸促进的亚芳基裂解。凭借这些知识,我们优化了可重现和高产的反应条件,确保并扩展了

  • Repairing the Thiol-Ene Coupling Reaction
    作者:Guillaume Povie、Anh-Tuan Tran、David Bonnaffé、Jacqueline Habegger、Zhaoyu Hu、Christine Le Narvor、Philippe Renaud

    日期:2014.4.7
    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.
  • Synthesis of a β-GlcN-(1→4)-MurNAc building block en route to N-deacetylated peptidoglycan fragments
    作者:Luigi Cirillo、Emiliano Bedini、Antonio Molinaro、Michelangelo Parrilli
    DOI:10.1016/j.tetlet.2009.12.124
    日期:2010.2
    Some bacteria present a variation in their peptidoglycan structure that is the absence of the N-acetyl substituent in the glucosamine residue. Very recently, this structural modification was demonstrated to be critical for host innate immune evasion in Listeria monocytogenes. To shed light on the molecular details of the evasion mechanism, the synthesis of some N-deacetylated peptidoglycan fragments is needed. En route to this goal a high-yielding synthesis of a GlcN-MurNAc disaccharide building block has been accomplished. A careful study of the optimal protecting groups and reaction conditions was done to have a complete beta-stereoselectivity in glycosylation as well as to ensure a high versatility to the disaccharide building block.
