  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.

  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.

  The intermolecular α-arylation of esters by palladium-catalyzed coupling of aryl bromides with zinc enolates of esters is reported. Reactions of three different types of zinc enolates have been developed. α-Arylation of esters occurs in high yields with isolated Reformatsky reagents, with Reformatsky reagents generated from α-bromo esters and activated zinc, and with zinc enolates generated by quenching

  报道了通过芳基溴化物与酯的烯醇锌的钯催化偶联实现酯的分子间α-芳基化。已经开发出三种不同类型的烯醇锌的反应。使用分离的 Reformatsky 试剂、使用由 α-溴代酯和活化锌生成的 Reformatsky 试剂以及使用氯化锌猝灭酯的碱金属烯醇化物生成的锌烯醇化物，可以高产率进行酯的 α-芳基化。使用烯醇锌代替碱金属烯醇化物大大扩展了酯的芳基化范围。该反应在室温或 70 °C 下与含有氰基、硝基、酯、酮、氟、烯醇化氢、羟基或氨基官能团的溴代芳烃以及与溴代吡啶发生。酯的范围包括无环乙酸酯、丙酸酯和异丁酸酯、α-烷氧基酯和内酯。使用带有受阻五苯基二茂铁基二叔丁基膦(Q-phos)或高反应性二聚Pd(I)络合物[P( t -Bu) 3 ]PdBr} 2 的催化剂进行酯的烯醇锌的芳基化。
