  摘要：

  植物寄生线虫是作物保护的主要威胁。缺乏具有新作用方式和增加的抗性的杀线虫剂提高了对新型杀线虫剂的需求。为了寻找新的杀线虫先导物，从查耳酮的结构出发，通过闭环设计策略得到了一系列稠环化合物。这些化合物被进一步修饰。评估了合成化合物对南方根结线虫的杀线虫活性。生物测定表明，化合物3及其一些衍生物如化合物18、19、21、22、23、24和26表现出优异的杀线虫活性。其中，化合物23表现出显着的生物活性。LC 50/72 小时体外值达到3.20 mg/L ，在基质中40 mg/L时抑制率为100.00%。详细讨论了合成化合物的构效关系。还评估了化合物23对秀丽隐杆线虫的卵孵化、运动和摄食行为的影响。

  The present invention describes 2-methyl-quinazoline compounds of general formula (I), methods of preparing said compounds, intermediate compounds useful for preparing said compounds, pharmaceutical compositions and combinations comprising said compounds, and the use of said compounds for manufacturing pharmaceutical compositions. The 2-methyl substituted quinazoline compounds of general formula(I) effectively and selectively inhibit the Ras-Sos interaction without significantly targeting the EGFR receptor. They are therefore useful for the treatment or prophylaxis of diseases, in particular of hyperproliferative disorders, such as cancer as a sole agent or in combination with other active ingredients.

  found to catalyze the direct arylation of some functionalized halothiophene derivatives allowing the synthesis in only one step of polyfunctionalized arylated thiophenes. In the presence of 2-acetyl-3-chlorothiophene, 2-acetyl-4-chlorothiophene, 2-acetyl-3-bromothiophene diethylacetal or 2-(4-bromothiophen-2-yl)-[1,3]dioxolane, and a variety of aryl bromides, the 5-arylation products were obtained

• Cyclopentyl Methyl Ether: An Alternative Solvent for Palladium-Catalyzed Direct Arylation of Heteroaromatics
  作者：Kassem Beydoun、Henri Doucet

  DOI：10.1002/cssc.201000405

  日期：2011.4.18

  Some ethers, such as cyclopentyl methyl ether and di‐n‐butyl ether, which can be considered as “greener” solvents than N,N‐dimethylacetamide (DMAc) or DMF, can be advantageously employed for the palladium‐catalyzed direct arylation of heteroaromatics. In the presence of such ethers and only 0.5–1 mol % of palladium catalysts at 125–150 °C, the direct 5‐arylation of thiazoles, thiophenes, or furans

  某些醚，例如环戊基甲基醚和二正丁基醚，可以被认为是比N，N-二甲基乙酰胺（DMAc）或DMF更“绿色”的溶剂，可有利地用于钯催化的杂芳族化合物的直接芳基化。在125-150°C的条件下，在存在此类醚和仅0.5-1 mol％的钯催化剂的情况下，通过使用芳基溴化物作为偶联伙伴，噻唑，噻吩或呋喃的直接5-芳基化反应将以中等至高收率进行。
