  3-Phenyl-5-methyl-2H,5H-furan-2-ones: tuning antifungal activity by varying substituents on the phenyl ring

  摘要：

  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.

  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.

• A donor–acceptor complex enables the synthesis of <i>E</i>-olefins from alcohols, amines and carboxylic acids

  Olefins are prevalent substrates and functionalities. The synthesis of olefins from readily available starting materials such as alcohols, amines and carboxylic acids is of great significance to address the sustainability concerns in organic synthesis. Metallaphotoredox-catalyzed defunctionalizations were reported to achieve such transformations under mild conditions. However, all these valuable strategies

  烯烃是普遍的底物和功能。从醇、胺和羧酸等易得起始原料合成烯烃对于解决有机合成中的可持续性问题具有重要意义。据报道，金属光氧化还原催化的去官能化可以在温和条件下实现这种转变。然而，所有这些有价值的策略都需要过渡金属催化剂、配体或昂贵的光催化剂，并且仍然存在控制区域选择性和立体选择性的挑战。在此，我们提出了一种由电子供体-受体（EDA）配合物实现的根本不同的策略，用于从这些简单且易于获得的起始材料选择性合成烯烃。该转化是通过用碱金属盐对活化底物的 EDA 络合物进行光活化，然后从原位生成的烷基自由基中消除氢原子来进行的。该方法操作简单直接，不含光催化剂和过渡金属，并表现出高区域选择性和立体选择性。

  The concomitant generation of a nucleophilic and an electrophilic site from unsaturated Weinreb amide by using Cp2Zr(H)Cl) as the unique reagent was developed to promote a cyclisation reaction. The access to trans-2-substituted cyclopentanols or cyclopentylhydroxylamines can be selectively driven by a judicious choice of the cyclisation promotor. An access to cis-3-substituted is also described.

In particular, the use of AcOEt, the solvent of choice for green sustainable reactions, led to the high reactivities of the present reactions. This methodology is highly recommended for green sustainable chemistry because it uses stable and non-hazardous

  3-[4-[(3-Chlorophenyl)methoxy]phenyl]-5-[(methylamino)methyl]- 2-oxazolidinone (1) is a secondary amine known to be a potent time-dependent irreversible inactivator of monoamine oxidase B (MAO-B). The primary amine analogues of derivatives of 1, as well as of the corresponding dihydrofuranone and pyrrolidinone, had been shown to be time-dependent, but reversible, inhibitors of MAO-B. Here it is shown
