  Substituent effects of cis-cinnamic acid analogues as plant growh inhibitors

  摘要：

  1-O-cis-Cinnamoyl-beta-D-glucopyranose is one of the most potent allelochemicals that has been isolated from Spiraea thunbergii Sieb by Hiradate et al. It derives its strong inhibitory activity from cis-cinnamic acid (cis-CA), which is crucial for phytotoxicity. By preparing and assaying a series of cis-CA analogues, it was previously found that the key features of cis-CA for lettuce root growth inhibition are a phenyl ring, cis-configuration of the alkene moiety, and carboxylic acid. On the basis of a structure-activity relationship study, the substituent effects on the aromatic ring of cis-CA were examined by systematic synthesis and the lettuce root growth inhibition assay of a series of cis-CA analogues having substituents on the aromatic ring. While ortho- and para-substituted analogues exhibited low potency in most cases, meta-substitution was not critical for potency, and analogues having a hydrophobic and sterically small substituent were more likely to be potent. Finally, several cis-CA analogues were found to be more potent root growth inhibitors than cis-CA. (C) 2013 Elsevier Ltd. All rights reserved.

  Supramolecular assistance of the regioselective synthesis of single dimers from [2 + 2] photoreactions surface-directed by multivalent H-bonding exo-templates based on hydrophilic carbon materials (HCMs) is highlighted for the first time. Supramolecular photochemistry of stilbenes assisted by either functionalized carbon nanotubes or sub-microspheres afforded a single rtct-isomer after two consecutive

  由基于亲水性碳材料（HCM）的多价H键外显子模板表面定向的[2 + 2]光反应区域选择性合成单二聚体的超分子辅助首次得到强调。在溶液中连续两个步骤（紫外线照射和水热异构化）后，由功能化的碳纳米管或亚微球辅助的对苯二甲酸酯的超分子光化学提供了一个单一的rtct-异构体。碳球显示出以中等至定量产率介导4-肉桂酸衍生物二聚化的能力。该结果可以通过溶液或通过碳球/肉桂衍生物组件的机械化学研磨辅助。由于表面上存在–COOH和–OH基团以及有效的碳模板：底物比率，因此将此类纳米材料的结构模板特征作为表面识别过程的函数进行了讨论。

  Photoisomerization of a series of substituted E-cinnamic acids in MeCN in their acid forms and as their corresponding protic ionic liquids (PILs) with light of 300 nm is studied. The nature, strength, number, and position effects of substituents on the photochemical behavior of E-cinnamic derivatives are investigated. The photosensitization of the reaction in the presence of Michler's ketone is also

  研究了MeCN中一系列取代的E-肉桂酸的酸形式及其相应的质子离子液体（PIL）在300 nm的光下的光异构化。研究了取代基的性质，强度，数量和位置对E-肉桂酸酯衍生物光化学行为的影响。还研究了在米氏酮存在下该反应的光敏化在366 nm的情况，这表明反应中涉及三重激发态。由于n的存在在所有情况下，形成PIL所需的丁胺都会显着提高光产物的产率，并讨论了PIL的作用。因此，对这些基本方面的理解已经使我们能够建立成功地合成Z-肉桂酸的优异且实用的合成方案。
