  通过钯催化的 C-H 官能化和苯甲酸的原脱羧合成对位取代芳烃的通用方法

  摘要：

  虽然已经开发了大量的邻位 C-H 官能化反应，并在间位 C-H 活化方面取得了一些突破，但对位 C-H 官能化仍处于起步阶段。在本文中，通过由钯催化的 C-H 官能化和随后的铜催化苯甲酸原脱羧组成的串联工艺开发了一种合成对位取代芳烃的通用策略。吸电子和给电子官能团都可以引入带有各种取代基的芳烃的对位。

  Chronobiotic activity of N-[2-(2,7-dimethoxyfluoren-9-yl)ethyl]-propanamide. Synthesis and melatonergic pharmacology of fluoren-9-ylethyl amides

  摘要：

  A series of fluoren-9-yl ethyl amides (2) were synthesized and evaluated for human melatonin MT1 and MT2 receptor binding. N-[2-(2,7-dimethoxyfluoren-9-yl)ethyl]propanamide (2b) was selected and evaluated in functional assays measuring intrinsic activity at the human MT1 and MT2 receptors and demonstrated full agonism at both receptors. The chronobiotic properties of 2b were demonstrated in both acute and chronic rat models where 2b produced an acute phase advance of 32 min at 1 mg/kg and chronically entrained free-running rats with a mean effective dose of 0.23 mg/kg. Compound 2b is significantly less efficacious than melatonin in constricting human coronary artery. (C) 2004 Elsevier Ltd. All rights reserved.

• Intramolecular Aromatic C–H Acyloxylation Enabled by Iron Photocatalysis

  日期：2020.2.21

  protocol for the intramolecular aromatic C-H oxygenation of 2-biphenylcarboxylic acids has been achieved via iron photocatalysis. The 2-biphenylcarboxylic acids with a diverse array of substituents at both phenyl rings could furnish the oxygenation products in good to excellent yields. We speculate that the aryl carboxylate-iron(III) complexes should generate the aroyloxy radicals and iron(II) upon visible

  photoactivated (−)-riboflavin (vitamin B2) to generate the heterocyclic core via photoinduced single electron transfer. Collectively, the inexpensive nature of the catalyst, ease of execution, and absence of external metal additives are a convincing endorsement for the incorporation of simple vitamins in contemporary catalysis.

  Herein we described an access to biaryl lactones from ortho-aryl benzoic acids via intramolecular O–H/C–H oxidative coupling with the commonly used cerium ammonium nitrate (CAN) as the one-electron oxidant under a thermal condition. The radical interrupting experiment suggested a radical process, while the kinetic isotope effect (KIE) showed that the C–H cleavage likely was not involved in the rate-determining

  在此，我们描述了从邻位获取联芳基内酯的方法-芳基苯甲酸通过分子内O-H / C-H氧化偶联与常用的硝酸铈铵（CAN）在热条件下作为单电子氧化剂。自由基中断实验表明了一个自由基过程，而动力学同位素效应 (KIE) 表明 C-H 裂解可能不参与速率决定步骤。竞争性反应，尤其是哈米特方程显着不同的 ρ 值，表明反应速率对芳基部分的电子性质比羧基部分的电子性质更敏感，这对应于第一个单电子转移 (SET) 步骤。此外，芳基部分的相当负的 ρ 值（-4.7）揭示了第二个分子内自由基加成过程的显着亲电性质，这也与产物产率和区域选择性一致。此外，对照实验揭示了第三步中的单电子也转移到了 CeIV代替分子氧。此外，还讨论了共溶剂三氟乙醇 (TFE) 的可能作用及其对 Ce IV物种的影响。这项工作通过提出对总反应速率和负责最后单电子转移的物种有更大影响的步骤来阐明可能的机制。
