• CuI-Promoted One-Pot Synthesis of N-Boc Protected β-Ketotriazole Amino Acids: Application in the Synthesis of New Class of Dipeptidomimetics

  日期：2012.3.1

  One-pot click chemistry of Nα-Boc-bromomethylketones, NaN3 and propiolic acid affords N-Boc protected 1,4- disubstituted 1,2,3-β-ketotriazole acids in good to excellent yield. The use of CuI as catalyst and DMSO as solvent leads the click reaction to efficient, practical and column-free preparation of the title compounds. The utility of the resulting unnatural amino acids as building blocks to prepare triazole possessing peptidomimetics is also delineated.

• Linear and cyclic β3-oligopeptides with functionalised side-chains (-CH2OBn, -CO2Bn, -CH2CH2CO2Bn) derived from serine and from aspartic and glutamic acid

  The natural β-amino acid derivative Boc-Asp(β-OH)-OBn, as well as Boc-β-HGlu(OBn)-OH and Boc-β-HSer(OBn)-OH (prepared from appropriately protected glutamic acid and serine, respectively, by Arndt–Eistert homologation), were employed as building blocks for the synthesis of linear (11–20) and cyclic (21–23) β-oligopeptides consisting of two to six β-amino acids [using trichloroethyl (TCE) ester groups for C-terminal protection and pentafluorophenyl-ester activation for macrocyclisation]. While the linear derivatives are soluble enough for reactions and structural investigations in solution, the cyclo-β-tri- and -hexapeptides are not (according to FT-IR measurements they form networks of hydrogen bonds, perhaps consisting of so-called nanotubes). The CD spectra of the Boc–OTCE-protected (19) and of the unprotected (20) β-hexapeptides [β-Asp(OBn)-β-HGlu(OBn)-β-HSer(OBn)]2 differ drastically, and only the unprotected form shows the familiar pattern of a negative Cotton effect between 210 and 220 nm (indicative of a 314 helix). An NMR analysis in methanol of the β-hexapeptide 20 with free termini reveals the presence of a single, central, left-handed helix turn (14-membered hydrogen-bonded ring). The results are discussed and compared with those obtained previously for analogous β-peptides carrying non-functionalised side chains.

  天然的β-氨基酸衍生物Boc-Asp(β-OH)-OBn，以及Boc-β-HGlu(OBn)-OH和Boc-β-HSer(OBn)-OH（分别通过Arndt-Eistert同系化法从适当保护的谷氨酸和丝氨酸制备），被用作合成由2到6个β-氨基酸组成的线性（11-20）和环状（21-23）β-寡肽的构建模块[使用三氯乙基（TCE）酯基团进行C端保护和五氟苯酯激活进行大环化]。尽管线性衍生物在溶液中足以用于反应和结构研究，但环状β-三肽和六肽则不然（根据FT-IR测量，它们形成了氢键网络，可能是由所谓的纳米管组成）。Boc-OTCE保护的六肽（19）和无保护的六肽（20）[β-Asp(OBn)-β-HGlu(OBn)-β-HSer(OBn)]2的CD光谱存在显著差异，只有无保护形式在210到220 nm之间显示熟悉的负Cotton效应模式（表明为314螺旋）。在甲醇中对自由末端的六肽20进行NMR分析揭示了存在一个中心、左旋的螺旋转弯（14元氢键环）。结果进行了讨论并与先前获得的具有非功能化侧链的类似β-肽的结果进行了比较。
