    描述了神经毒性的毒扁豆碱生物碱d,1-塞孔的简明合成,其依赖于分子内环加成反应,该反应涉及“未稳定的”亚氨酸酯亚甲基和未活化的烯烃。通过偶合和偶极亲和体在芳基核上的邻位排列加强的刚性排列,增强了这种环化的便利性。在尝试合成赤藓骨架的过程中揭示了这种环形方法的合成局限性。在这种情况下,亚胺酸酯亚甲基的质子性重排为异构烯胺,从而排除了所需的环化反应。

  • Click Chemistry Approach to New N-Substituted Aminocyclitols as Potential Pharmacological Chaperones for Gaucher Disease
    作者:Lucía Díaz、Jordi Bujons、Josefina Casas、Amadeu Llebaria、Antonio Delgado
    DOI:10.1021/jm100198t
    日期:2010.7.22
    New N-alkylaminocyclitols bearing a 1,2,3-triazole system at different positions of the alkyl chain have been prepared as potential GCase pharmacological chaperones using click chemistry approaches. Among them, compounds 1d and 1e, with the shorter spacer (n = 1) between the alkyltriazolyl system and the aminocyclitol core, were the most active ones as GCase inhibitors, revealing a determinant effect
    已经使用点击化学方法制备了在烷基链的不同位置带有1,2,3-三唑系统的新的N-烷基氨基环醇,作为潜在的GCase药理伴侣。其中,化合物1d和1e具有较短的间隔基(n= 1)在烷基三唑基系统和氨基环糖醇核心之间,是最活跃的GCase抑制剂,显示了三唑环位置对活性的决定性作用。此外,SAR数据和计算对接模型表明了亲脂性和酶抑制之间的相关性,并提出了化合物的“扩展”和“弯曲”潜在结合模式。在“弯曲”模式下,活性最高的化合物可以在三唑部分和酶残基Q284之间建立氢键相互作用。在三唑和氨基环糖醇核心之间具有更长间隔基的化合物中,将排除这种相互作用。
  • Brønsted Acid Catalysis in Visible-Light-Induced [2+2] Photocycloaddition Reactions of Enone Dithianes
    作者:Christoph Brenninger、Alexander Pöthig、Thorsten Bach
    DOI:10.1002/anie.201700837
    日期:2017.4.3
    1,3-Dithiane-protected enones (enone dithianes) were found to undergo an intramolecular [2+2] photocycloaddition under visible-light irradiation (λ=405 nm) in the presence of a Brønsted acid (7.5-10 mol %). Key to the success of the reaction is presumably the formation of colored thionium ions, which are intermediates of the catalytic cycle. Cyclobutanes were thus obtained in very good yields (78-90 %)
    发现 1,3-二噻烷保护的烯酮(烯酮二噻烷)在可见光照射(λ=405 nm)下、在布朗斯台德酸(7.5-10 mol%)存在下发生分子内 [2+2] 光环加成。该反应成功的关键可能是有色锍离子的形成,它们是催化循环的中间体。由此以非常好的收率(78-90%)获得环丁烷。还表明,二噻烷部分可以被还原或氧化去除,而不影响光化学构建的环骨架。
  • Tailored Pyridoxal Probes Unravel Novel Cofactor‐Dependent Targets and Antibiotic Hits in Critical Bacterial Pathogens
    作者:Martin Pfanzelt、Thomas E. Maher、Ramona M. Absmeier、Markus Schwarz、Stephan A. Sieber
    DOI:10.1002/anie.202117724
    日期:2022.6.13
    Unprecedented targets are needed to fight the bacterial pandemic. A suite of pyridoxal probes that infiltrate the cellular metabolism of critical pathogens and get incorporated in pyridoxal-phosphate dependent enzymes is applied. Chemoproteomics facilitated the functional characterization of previously unknown members and the identification of essential targets with antibiotic hit molecules.

  • Nanomolar E-Selectin Antagonists with Prolonged Half-Lives by a Fragment-Based Approach
    作者:Jonas Egger、Céline Weckerle、Brian Cutting、Oliver Schwardt、Said Rabbani、Katrin Lemme、Beat Ernst
    DOI:10.1021/ja4029582
    日期:2013.7.3
    Selectins, a family of C-type lectins, play a key role in inflammatory diseases (e.g., asthma and arthritis). However, the only millimolar affinity of sialyl Lewis(x) (sLe(x)), which is the common tetrasaccharide epitope of all physiological selectin ligands, has been a major obstacle to the development of selectin antagonists for therapeutic applications. In a fragment-based approach guided by NMR, ligands binding to a second site in close proximity to a sLe(x) mimic were identified. A library of antagonists obtained by connecting the sLe(x) mimic to the best second-site ligand via triazole linkers of different lengths was evaluated by surface plasmon resonance. Detailed analysis of the five most promising candidates revealed antagonists with K-D values ranging from 30 to 89 nM. In contrast to carbohydratelectin complexes with typical half-lives (t(1/2)) in the range of one second or even less, these fragment-based selectin antagonists show t(1/2) of several minutes. They exhibit a promising starting point for the development of novel anti-inflammatory drugs.
  • Alkaloid synthesis via the intramolecular imidate methylide 1,3-dipolar cycloaddition reaction
    作者:Richard Smith、Tom Livinghouse
    DOI:10.1016/s0040-4020(01)96709-2
    日期:1985.1
    A concise synthesis for the neurotoxic physostigmine alkaloid d,l-eserethole is described which relys upon an intramolecular cycloaddition reaction involving a “non-stabilized” imidate methylide and an unactivated alkene. The facility of this cyclization is enhanced by the rigid alignment inforced upon the dipole and dipolarophile by their ortho-disposition on an aryl nucleus. The synthetic limitations
