  Design, synthesis, and antifungal activity of inhibitors of brassilexin detoxification in the plant pathogenic fungus Leptosphaeria maculans

  摘要：

  Potential inhibitors of Leptosphaeria maculans mediated detoxification of the phytoalexin brassilexin were designed and synthesized based on the planar heteroaromatic structure of isothiazolo[5,4-b]indole. Screening of these compounds for inhibition of brassilexin detoxification in cultures of L. maculans indicated that 4-(2-chlorophenyl)isothiazole had the largest effect on the rate of brassilexin detoxification. However, the most antifungal compound among the potential inhibitors, isothiazolo[5,4-b]quinoline, did not appear to affect the metabolism of brassilexin noticeably, suggesting that growth inhibition is not sufficient to slow down the rate of brassilexin detoxification. Furthermore, it was determined that 4-arylisothiazoles as well as isothiazolo[5,4-b]thianaphthene displayed antifungal activity against L. maculans. (c) 2005 Elsevier Ltd. All rights reserved.

  annulation protocol combining, in one pot, a direct arylation and cross aldol condensation for the straightforward synthesis at gram-scale of π-extended thiophene-based scaffolds. The regiospecific direct arylation drives the subsequent cross-aldol condensation proceed under the same basic conditions, and the overall protocol has broad applicability in the synthesis of extended aromatics wherein the thiophene

  cyclopentene‐fused heteroarenes by means of the Pd‐catalyzed Trost–Oppolzer‐type intramolecular Alder–ene reaction of 2,4‐pentadienyl acetates is described. This unprecedented transformation combines the electrophilic features of the Tsuji–Trost reaction with the nucleophilic features of the Alder–ene reaction. The overall outcome can be perceived as a hitherto unknown “acid‐free” iso‐Nazarov‐type cyclization. The

  A reliable synthetic protocol toward a series of fused chalcogenopheno[1]benzochalcogenophene (CBC) building blocks was developed based on a Fiesselmann reaction. The obtained CBC units were applied in McMurry and Stille coupling reactions toward symmetric regioisomeric ene-linked dimers. These π-conjugated compounds were characterized regarding their photophysical and electrochemical properties and

  基于Fiesselmann反应，开发了一种可靠的合成方案，适用于一系列融合的硫族硫属元素[1]苯并硫属元素金属（CBC）构建基块。将获得的CBC单元应用于McMurry和Stille偶联反应中，用于对称的区域异构烯连接的二聚体。这些π-共轭化合物的光物理和电化学特性得到了表征，并且被证明是与基于硫的类似物相比具有减小的HOMO-LUMO间隙的材料。X射线单晶衍射实验表明，强分子间硒-硒和硒-碳相互作用取决于结合的硒原子的位置和数量。可以观察到良好的场效应晶体管性能，电荷载流子迁移率高达4×10-3 cm2 V-1 s-1，并且开/关比高。

  control of halide substitution at six of the seven naphthalene positions of 2‐arylnaphthalenes is achieved through the regioselective benzannulation of chloro‐, bromo‐, and iodoalkynes. The modularity of this approach is demonstrated through the preparation of 44 polyheterohalogenated naphthalene products, most of which are difficult to access through known naphthalene syntheses. The outstanding regioselectivity

  通过氯，溴和碘炔的区域选择性苯环烷基化，可以实现2-芳基萘七个萘位置中六个位置上卤化物取代的独立控制。该方法的模块化通过制备44种多卤代萘产品得到了证明，其中大多数产品都难以通过已知的萘合成方法获得。对于许多实例，反应的出色区域选择性既可以预测，也可以通过单晶X射线衍射明确证明。这种合成方法能够使用已建立的交叉偶联方法快速制备准备进一步衍生化的复杂芳香族体系。
