  摘要：

  某些G蛋白偶联受体（GPCR）的配体已被鉴定为内源性脂质，例如溶血磷脂酰丝氨酸（LysoPS）。在这里，我们分析了LysoPS受体亚型之一的GPR34配体的结构-活性关系的分子基础，重点是疏水口袋对长链脂肪酸部分的识别。通过将苯环引入2-脱氧的脂肪酸部分-LysoPS，我们探索了结合位点对疏水形状的偏好。具有末端芳族部分的修饰的含三苯的脂肪酸替代物显示出对GPR34的有效激动活性。这些衍生物与基于GPR34的同源性建模/基于分子动力学的虚拟结合位点的计算对接表明，基于苯的脂质替代物中的纽结与GPR34的L形疏水口袋相匹配。在末端苯环的4-位带有庞大的叔丁基的基于四苯的脂质类似物表现出强效的GPR34激动活性，证实了本发明的疏水结合口袋模型。

A wide range of 2-arylbenzoyl fluoride derivatives can be used as fluorenone precursors and the reaction proceeds via an intramolecular coupling between aromatic C–H bonds with acyl C–F bonds.

• Electronic Conduction in Biphenyl Liquid Crystals
  作者：Kensuke Kurotaki、Hideaki Haruyama、Yukiko Takayashiki、Jun-ichi Hanna

  DOI：10.1246/cl.2006.1194

  日期：2006.10

  A series of 4-alkyl-4′-alkoxylbiphenyls, which are one of the representative calamitic liquid crystals having a small aromatic core moiety, has been synthesized and their charge carrier transport properties are characterized in order to examine how small the core size can be for a high mobility. The biphenyls exhibit both smectic B and E phases and the hole transport characterized by a high mobility of 10−3 cm2 V−1 s−1 in the smectic mesophases. The mobility depends on temperature in both smectic phases, and furthermore it depends on the electric field in the smectic E phase. The fact that such a small molecule of biphenyl exhibits the mobility comparable to those of triphenylenes and TPD (N,N′-diphenyl-N,N′-bis(3-methylphenyl)[1,1′-biphenyl]-4,4′-diamine) gives an insight into the molecular design of high mobility liquid crystalline materials.

  合成了一系列4-烷基-4′-烷氧基联苯，它们是具有小芳香核心部分的代表性棒状液晶之一，并测定了其载流子传输性质，以考察核心尺寸小到何种程度才能具有高迁移率。这些联苯同时呈现层列B相和E相，层列介晶相中的空穴传输性质以高迁移率为特征，达到10−3 cm2 V−1 s−1。迁移率在两种层列相中均依赖于温度，而且在层列E相中还依赖于电场。如此小的联苯分子，其迁移率可与三联苯和TPD（N,N′-二苯基-N,N′-双(3-甲基苯基)[1,1′-联苯]-4,4′-二胺）相媲美，这一事实为高迁移率液晶材料的分子设计提供了见解。
• Access to 3‐(2‐Oxoalkyl)‐azaspiro[4.5]trienones <i>via</i> Acid‐Triggered Oxidative Cascade Reaction through Alkenyl Peroxide Radical Intermediate
  作者：Chang‐Sheng Wang、Thierry Roisnel、Pierre H. Dixneuf、Jean‐François Soulé

  日期：2019.2

  Azaspiro[4.5]trienones bearing ketone side chains at the 3‐position are prepared from N‐alkyl‐arylpropiolamides and ketones via oxidative 1,2‐difunctionalization of alkynes. The cascade sequence starts with the generation of alkenyl peroxide intermediates, which are obtained by addition of tert‐butyl hydroperoxide to ketones in presence of a catalytic amount of a strong acid. Then, the ketone radical adds to
