  [reaction: see text] A sequential solid-phase peptide synthesis was developed using both photolabile linker and protecting groups. The chromatic sequential lability between a tert-butyl ketone-derived linker (sensitive to irradiation at 305 nm) and a nitroveratryloxycarbonyl (NVOC) group (sensitive at 360 nm) was exploited to prepare Leu-Enkephalin in a 55% overall yield. This new strategy allows the

  作者：J. Y. Roberge、X. Beebe、S. J. Danishefsky

  DOI：10.1021/ja9740071

  日期：1998.4.1

  Oligosaccharides and glycopeptides are of considerable importance in molecular biology and pharmacology. However, their synthesis is complicated by the large number of different linking sites between each saccharide unit, the need for stereochemical control, the chemical sensitivity of the glycopeptide bonds, and the need to harmonize diverse protecting groups. Here, an efficient solid-phase synthesis of three

  寡糖和糖肽在分子生物学和药理学中具有相当重要的意义。然而，由于每个糖单元之间有大量不同的连接位点、需要立体化学控制、糖肽键的化学敏感性以及协调不同保护基团的需要，它们的合成变得复杂。在这里，提出了一种基于糖组装的三种 N 连接糖肽的有效固相合成。肽域可以扩展，而整体保持与聚合物结合。这里合成的糖肽是迄今为止通过溶液或固相合成获得的最大的 N 连接糖肽之一。
• The 2-(Triphenylsilyl)ethoxycarbonyl-(“Tpseoc”-) Group: A New Silicon-Based, Fluoride Cleavable Oxycarbonyl Protecting Group Highly Orthogonal to the Boc-, Fmoc- and Cbz-Groups
  作者：Martin Golkowski、Thomas Ziegler

  DOI：10.3390/molecules16064695

  日期：——

  Starting from 2-(triphenylsilyl)ethanol a new oxycarbonyl protecting group cleavable by fluoride ion induced Peterson-elimination has been developed. Known 2-(triphenylsilyl)ethanol has been prepared from commercially available triphenylvinyl-silane by a hydroboration-oxidation sequence using the sterically hindered borane reagent 9-BBN. The silyl alcohol was subsequently transformed into its chloroformate

  从 2-（三苯基甲硅烷基）乙醇开始，开发了一种新的氧羰基保护基团，该基团可通过氟离子诱导的彼得森消除来裂解。已知的 2-(三苯基甲硅烷基)乙醇是通过使用空间位阻硼烷试剂 9-BBN 的硼氢化-氧化序列从市售的三苯基乙烯基硅烷制备的。随后将甲硅烷醇转化为其氯甲酸酯、咪唑基羧酸酯和对硝基苯基碳酸酯，并用于形成氨基甲酸酯和碳酸酯的标准方案。事实证明，Tpseoc 基团对用于去除叔丁酯和 t-Boc 基团的酸性条件具有很强的抵抗力。它还经受住了催化氢化、用吗啉、甲基肼和 Pd-试剂/烯丙基-清除剂组合的处理，以及裂解 Cbz-、Fmoc-、邻苯二甲酰亚胺和 Alloc 基团。Tpseoc-基团在 0°C 或室温下用 TBAF/CsF 处理后裂解，裂解时间从 <10 分钟起。到 24 小时。其正交性、易于裂解和紫外检测能力使 Tpseoc-基团成为其他广泛使用的硅基胺保护基团（如 Teoc-和 SES-基团）的有前途的替代品。

Lysobactin, a depsipeptide antibiotic has displayed very strong antibacterial activity against methicillin-resistant Staphylococcus aureus (MRSA) as well as vancomycin-resistant enterococci (VRE) with minimum inhibitory concentrations (MICs) ranging from 0.39 to 0.78 μg/mL. The MIC values against VRE were more than 50-fold lower than those reported for vancomycin itself. Lysobactin was found
