  Finding new elicitors that induce resistance in rice to the white-backed planthopper Sogatella furcifera

  摘要：

  Herein we report a new way to identify chemical elicitors that induce resistance in rice to herbivores. Using this method, by quantifying the induction of chemicals for GUS activity in a specific screening system that we established previously, 5 candidate elicitors were selected from the 29 designed and synthesized phenoxyalkanoic acid derivatives. Bioassays confirmed that these candidate elicitors could induce plant defense and then repel feeding of white-backed planthopper Sogatella furcifera. (C) 2015 Elsevier Ltd. All rights reserved.

  Suitably functionalised carboxylic acids undergo a previously unknown photoredox reaction when irradiated with UVA in the presence of maleimide. Maleimide was found to synergistically act as a radical generating photoxidant and as a radical acceptor, negating the need for an extrinsic photoredox catalyst.

  redox-neutral method for nucleophilic fluorination of N-hydroxyphthalimide esters using an Ir photocatalyst under visible light irradiation. The method provides access to a broad range of aliphatic fluorides, including primary, secondary, and tertiary benzylic fluorides as well as unactivated tertiary fluorides, that are typically inaccessible by nucleophilic fluorination due to competing elimination

  我们报告了在可见光照射下使用 Ir 光催化剂对 N-羟基邻苯二甲酰亚胺酯进行亲核氟化的氧化还原中性方法。该方法提供了获得广泛的脂肪族氟化物的途径，包括伯、仲和叔苄基氟化物以及未活化的叔氟化物，由于竞争消除，这些氟化物通常无法通过亲核氟化获得。此外，我们表明脱羧氟化条件很容易适应 [18F]KF 的放射性氟化。我们建议反应通过 Ir 催化剂和氧化还原活性酯底物之间的两次电子转移进行，以提供碳阳离子中间体，随后被氟化物捕获。

Structural modifications with a large number of each class confirm our earlier work that the highest activity is observed with compounds that contain dihalogenated aromatic rings with attached polar side chains.

  使用 TiO 2 的光化学反应和羧酸在干燥厌氧条件下导致几种类型的 C-C 键形成过程与缺电子烯烃。烷基化的效率随羧酸中的取代基而显着变化。芳氧基乙酸与马来酰亚胺的反应导致了一个级联过程，其中吡咯并色烯衍生物伴随着烷基化的琥珀酰亚胺。通过在不同条件下使用光氧化还原催化剂，可以在一定程度上调整这些产品中的一种或其他产品的选择性。通过包含 2-烯基、2-芳基或 2-肟基官能团而适用于分子内闭环的芳氧基乙酸反应相当差。这些系统的反应物消耗和产物形成的概况是通过原位核磁共振监测技术获得的。对一系列不同的催化剂形式进行了效率和易用性测试。所提出的机制，涉及在 TiO2 上的空穴捕获2表面由羧酸盐随后 CO 2损失得到中间体的 EPR 光谱证据的支持。氘标记表明二氧化钛可能从表面羟基提供质子并提供电子和空穴，因此既是催化剂又是反应伙伴。
