  Synthesis and structure–antifungal activity Relationships of 3-Aryl-5-alkyl-2,5-dihydrofuran-2-ones and Their Carbanalogues: further refinement of tentative pharmacophore group

  摘要：

  Two series of 3-(substituted phenyl)-5-alkyl-2,5-dihydrofuran-2-ones related to a natural product, (-)incrustoporine, were synthesized and their in vitro antifungal activity evaluated. The compounds with halogen substituents on the phenyl ring exhibited selective antifungal activity against the filamentous strains of Absidia corymbifera and Aspergillus fumigatus. On the other hand, the influence of the lenghth of the alkyl chain at C(5) was marginal. The antifungal effect of the most active compound against the above strains was higher than that of ketoconazole, and close to that of amphotericin B. In order to verify the hypothesis about a possible relationship between the Michael-accepting ability of the compounds and their antifungal activity, a series of simple carbanalogues, 2-(substituted phenyl)cyclopent-2-enones, was prepared and subjected to antifungal activity assay as well.

• Carbon–carbon bond-forming reactions of α-carbonyl carbocations: exploration of a reversed-polarity equivalent of enolate chemistry
  作者：Ping-Shan Lai、Joshua A. Dubland、Mohammed G. Sarwar、Michael G. Chudzinski、Mark S. Taylor

  日期：2011.9

  Carbon–carbon bond-forming reactions of putative α-carbonyl carbocation intermediates generated by Lewis acid- or silver-promoted ionizations of toluenesulfonate or halide leaving groups are described. This under-exploited mode of reactivity represents an ‘umpolung’ of conventional enolate chemistry, and enables C–C bond construction in both intra- and intermolecular contexts. Attempts to develop diastereoselective

  描述了由路易斯酸或银促进的甲苯磺酸盐或卤化物离去基团的电离产生的推定的α-羰基碳正离子中间体的碳-碳键形成反应。这种未充分利用的反应方式代表了常规烯醇式化学的“发展”，并在分子内和分子间环境下实现了C–C键的构建。讨论了尝试使用手性酯和基于恶唑烷酮的助剂开发该方法的非对映选择性变体的尝试。

  日期：2010.11.19

  A highly diastereoselective synthesis of trans-2-substituted cyclopentylamines via a tandem hydrozirconation/Lewis acid-mediated cyclization sequence applied to butenyl oxazolidines is described. The method allows an easy preparation of diversely substituted cyclopentylamines which appear to be useful synthetic intermediates. This was further illustrated by the syntheses of (±)-Rodocaine, (±)-trans-pentacin

  α-arylation reaction of Meyers’s chiral bicyclic lactams (MCBLs) under palladium catalysis, and a substrate-dependent post-transformation. When the bridgehead carbon of the MCBLs is substituted with a methyl or an ethyl group, the initial arylation product undergoes a further rearrangement reaction to give a conjugated framework. On the other hand, substrates bearing a bridgehead isopropyl or aryl group are

  描述了 Meyers 手性双环内酰胺 (MCBL) 在钯催化下的去质子 α-芳基化反应，以及底物依赖性后转化。当MCBL的桥头碳被甲基或乙基取代时，最初的芳基化产物经历进一步的重排反应，得到共轭骨架。另一方面，带有桥头异丙基或芳基的底物被转化成相应的外芳基化产物。初步研究表明，重排途径是通过去质子化促进的，并且不依赖于钯催化。除了机械兴趣之外，这项研究还展示了功能化内酰胺的模块化和发散合成。
• First Iodine-Catalyzed Deallylation of Reactive Allyl Methylene Esters

  DOI：10.1080/00397911.2012.682245

  日期：2013.7.18

  C-Allyl cleavage has been developed using the inexpensive and mild reagent iodine in dimethylsulfoxide. A variety of compounds with active methylene groups were C-deallylated using this reagent. This method is efficient and operationally simple in comparison to the methods using transition-metal complexes. Supplemental materials are available for this article.

• 3-Phenyl-5-methyl-2H,5H-furan-2-ones: tuning antifungal activity by varying substituents on the phenyl ring
  作者：Milan Pour、Marcel Špulák、Vojtěch Balšánek、Jiřı́ Kuneš、Vladimı́r Buchta、Karel Waisser

  A series of racemic 3-phenyl-5-methyl-2H,5H-furan-2-ones related to a natural product, (-)incrustoporine, was synthesized, and their antifungal activity evaluated. The key structural feature, furanone ring, was closed via H2SO4-mediated cyclization of 3-phenylpent-4-enoic acids. The compounds displayed antifungal activity, especially against filamentous fungi. Expressed as the minimum inhibition concentration (MIC) in mu mol/L, the activity of the most promising derivative against Absidia corymbifera matched that of ketoconazole (31.25 mu mol/L). In terms of mu g/mL, the substance was more active (7.6 mu g/mL) than this standard antifungal drug (16.6 mu g/mL). (C) 2000 Elsevier Science Ltd. All rights reserved.
