  Synthesis and anticancer activities of 3-arylflavone-8-acetic acid derivatives

  摘要：

  This paper describes the synthesis and the antiproliferative activities of compounds 9a-r, 3-aryl analogs of flavone-8-acetic acid that bear diverse substituents on the benzene rings at the 2- and 3-positions of the flavone nucleus. Their direct and indirect cytotoxicities were evaluated against HT-29 human colon adenocarcinoma cell lines, A549 lung adenocarcinoma cell lines and Human Peripheral Blood Mononuclear Cells (HPBMCs). The results indicate that most of the compounds bearing electron-withdrawing substituents (9b-m) exhibited moderate direct cytotoxicities. And compounds 9e and 9i showed comparable indirect cytotoxicities with 5, 6-dimethylxanthenone-4-acetic acid (DMXAA), and low direct cytotoxicities toward HPBMCs. Interestingly, the compounds 9n-r bearing methoxy groups at the 2- or 3-position of the flavone nucleus exhibited higher indirect cytotoxicities against A549 cell lines than DMXAA, and lower cytotoxicities against HPBMCs. In addition, compounds 9p-r were found to be able to induce tumor necrosis factor alpha (TNF-alpha) production in HPBMCs. (C) 2014 Elsevier Masson SAS. All rights reserved.

• Iridium-Catalyzed and Ligand-Controlled Carbonylative Synthesis of Flavones from Simple Phenols and Internal Alkynes

  Flavones are important natural products with diverse biological activities. In this study, a novel procedure for the carbonylative synthesis of flavones has been developed by using simple phenols and internal alkynes as the substrates. Various flavones were isolated in moderate to good yields with excellent regioselectivity and functional group tolerance by using an iridium catalyst system. Notably

  黄酮是具有多种生物活性的重要天然产物。在这项研究中，通过使用简单的苯酚和内部炔烃作为底物，开发了一种黄酮羰基合成的新方法。通过使用铱催化剂体系，以中度到良好的收率分离出各种黄酮，具有出色的区域选择性和官能团耐受性。值得注意的是，这是直接将未预活化的苯酚和炔烃进行羰基环化以生成黄酮的例子，而配体的选择对这种转化的成功至关重要。

  日期：2016.2.4

  An unexpected palladium‐catalyzed carbonylative synthesis of 2,3‐disubstituted chromones has been developed. Starting from 2‐bromofluorobenzenes and ketones, the corresponding chromones were produced in good yields. By control experiments, this transformation was found to proceed through a sequential carbonylation/Claisen–Hasse rearrangement/intramolecular nucleophilic aromatic substitution approach

  已经开发出了出乎意料的钯催化的2,3-二取代色酮的羰基合成。从2-溴氟苯和酮开始，以高收率生产了相应的色酮。由对照实验中，这种转变被发现通过连续的羰基化/克莱森-哈斯重排/分子内的亲核芳香取代的方法（S进行Ñ AR）。更具体地说，反应顺序始于酮与邻溴氟苯的钯催化羰基化反应，得到乙烯基苯甲酸酯，随后通过克莱森-哈斯重排将其转化为1,3-二酮。最终产物的分子内年代后产生Ñ的氩反应原位形成1,3-二酮。

  The Ni-catalyzed C−O/O−H annulation of salicylate esters with alkynes, leading to the production of chromone derivatives is reported. The key step in the reaction is the cleavage of an acyl C-O bond. The presence of a base is essential for the reaction to proceed.
