  • Synthesis of libraries of thiazole, oxazole and imidazole-based cyclic peptides from azole-based amino acids. A new synthetic approach to bistratamides and didmolamides
    作者:Anna Bertram、Nakia Maulucci、Olivia M. New、Siti Mariam Mohd Nor、Gerald Pattenden

    日期:——
    Treatment of a 1 : 1 mixture of the thiazole-based amino acids 8a and 8b with FDPP–i-Pr2NEt in CH3CN gave a mixture of the cyclic trimers 14, 15, 16 and 17 and the cyclic tetramers 19 and 23 in the ratio 2 : 7 : 5 : 8 : 1 : 1 and in a combined yield of 70%. Separate coupling reactions between the bisimidazole amino acid 45 and the thiazole/oxazole amino acids 43a and 42a in the presence of FDPP–i-Pr2NEt led to the bisimidazole based cyclic trimers 55 and 57 respectively (54–57%) and to the cyclic tetramer 56 (8–11%). Similar coupling reactions involving the bisthiazole and bisoxazole amino acids 49 and 47 with the imidazole/oxazole/thiazole amino acids 41a, 42a and 43a gave rise to the library of oxazole, thiazole and imidazole-based cyclic peptides 58, 59, 60, 61, 62, 63, 64 and 65. A coupling reaction between the bisthiazole amino acid 49 and the oxazole amino acid 73 led to an efficient (36% overall) synthesis of bistratamide H (67) found in the ascidian Lissoclinum bistratum. Coupling reactions involving oxazolines with thiazole amino acids were less successful. Thus, a coupling reaction between the phenylalanine-based oxazoline amino acid 71a and either the thiazole amino acid 8a or the bisthiazole amino acid 74 gave only a 2% yield of the cyclic hexapeptide didmolamide A (4) found in the ascidian Didemnum molle. Didmolamide B (68) was obtained in 9% yield from a coupling reaction between 74 and the phenylalanine threonine amino acid 72, using either FDPP or DPPA.
    噻唑氨基酸8a和8b的1:1混合物与FDPP-i-Pr2NEt在CH3CN中处理,得到了环状三聚体14、15、16和17以及环状四聚体19和23的混合物,其比例为2:7:5:8:1:1,总产率为70%。在FDPP-i-Pr2NEt存在下,双咪唑氨基酸45与噻唑/噁唑氨基酸43a和42a分别进行的单独偶联反应,分别得到了双咪唑基环状三聚体55和57(产率54-57%)以及环状四聚体56(产率8-11%)。类似地,双噻唑和双噁唑氨基酸49和47与咪唑/噁唑/噻唑氨基酸41a、42a和43a进行的偶联反应,生成了噁唑噻唑咪唑基环状肽库58、59、60、61、62、63、64和65。双噻唑氨基酸49与噁唑氨基酸73之间的偶联反应,高效(总产率36%)合成了在海鞘Lissoclinum bistratum中发现的双层板H(67)。含有噻唑氨基酸噁唑啉的偶联反应效果较差。因此,苯丙酸基噁唑氨基酸71a与噻唑氨基酸8a或双噻唑氨基酸74之间的偶联反应,仅得到了在海鞘Didemnum molle中发现的环状六肽didmolamide A(4),产率仅为2%。使用FDPPDPPA,从74与苯丙酸苏氨基酸72的偶联反应中获得了产率为9%的didmolamide B(68)。
  • Anion Recognition by Neutral Macrocyclic Azole Amides
    作者:Markus Schnopp、Silvia Ernst、Gebhard Haberhauer
    DOI:10.1002/ejoc.200800811
    日期:2009.1
    straightforward synthesis of C2-symmetric azole-containing macrocyclic peptides is presented. This type of macrocycle possesses four amide groups directed into the interior of the scaffold that act as hydrogen-bond donors and two nitrogen atoms from the azole unit that act as hydrogen-bond acceptors. This arrangement makes them sensitive receptors for Y-shaped anions like AcO– and H2PO4– with a selectivity for dihydrogen

    syntheses of C4- and a C2-sym. scaffolds I (X = Y = NH; X = O, Y = NH; X = Y =O) are presented. The synthesis of the key building block for both systems has been fundamentally improved. Starting from these scaffolds, various platforms possessing two or four arms can easily be prepd. The structures of the scaffolds, together with that of a C4-sym. oxazole scaffold, were investigated in the solid state and in

  • Structural investigation of westiellamide analogues
    作者:Gebhard Haberhauer、Eugen Drosdow、Thomas Oeser、Frank Rominger
    DOI:10.1016/j.tet.2007.11.098
    日期:2008.2
    The synthesis of westiellamide analogues, wherein the oxazoline units are replaced by oxazole or thiazole units, is presented. The structures of these analogues, and also of an imidazole-based analogue, were investigated using X-ray diffraction and DFT-based molecular modelling calculations. We could show that the oxazole-based peptide is almost planar, whereas the thiazole and the imidazole cyclic
    提出了其中甲恶唑啉单元被恶唑噻唑单元代替的西乙酰胺类似物的合成。使用X射线衍射和基于DFT的分子模型计算研究了这些类似物以及基于咪唑的类似物的结构。我们可以证明基于恶唑的肽几乎是平面的,而噻唑咪唑环肽则具有视锥状结构。此外,我们可以证明系统的灵活性主要取决于唑结构单元的类型。如果使用含恶唑的环肽,则支架具有几乎为平面的结构;如果没有,则为支架。然而,将支架弯曲成锥形结构需要高能量。含咪唑的环肽表现出互补的行为:

    DOI:10.1016/j.tetlet.2024.154916
    日期:2024.2
    Scalable total syntheses of Bistratamides H and J with remarkable yields of 22.9 % and 24.2 % over 9 steps, respectively, have been accomplished. The key step features a PPh3-promoted cascade reaction (disulfide cleavage/thiocarbonylation/intramolecular Staudinger-aza-Wittig reaction/dehydrogenation) to construct the key Boc-l-Val-thiazole fragment, DAST-promoted oxazoline synthesis, and a PyBOP-assisted
