  developed for the synthesis of 2-acylquinolines from methyl ketones and arylamines using 1,4-dithane-2,5-diol as an ethylene surrogate. Moreover, the investigation of the mechanism suggested that this reaction occurred via an iodination/Kornblum oxidation/Povarov/aromatization sequence. It is noteworthy that the arylamine substrate also played an important role in promoting the reaction.

  acylation of quinolines and isoquinolines is described by use of arylmethanols as the acylating agents through a C–C bond formation via an oxidative cross-dehydrogenative coupling (CDC) strategy. This C-aroylation reaction was carried out by use of K2S2O8 as oxidant and methyltrioctylammonium chloride (Aliquat 336) as a transfer agent in MeCN at 80 °C under transition-metal-free conditions.

  通过使用芳基甲醇作为酰化剂，通过氧化交叉脱氢偶联 (CDC) 策略形成 C-C 键，描述了喹啉和异喹啉的有效酰化。该 C-芳酰化反应是通过使用 K2S2O8 作为氧化剂和甲基三辛基氯化铵 (Aliquat 336) 作为转移剂在 80°C 下在无过渡金属条件下在 MeCN 中进行的。

  Acylation of electron-deficient heteroaromatic compounds has been developed using visible light. α-Ketoacids have been used as an efficient source of acyl radicals under photoredox conditions. The in situ generated acyl radicals from α-ketoacids have been coupled to a wide variety of electron-deficient heteroaromatic compounds in a Minisci type reaction. This method would be attractive to access biologically

  利用可见光已经开发出了缺电子的杂芳族化合物的酰化剂。在光氧化还原条件下，α-酮酸已被用作酰基的有效来源。在Minisci型反应中，由α-酮酸原位生成的酰基已与多种电子不足的杂芳族化合物偶联。该方法对于获得生物学上有吸引力的分子将是有吸引力的。

  日期：2015.6.5

  coupling between electron-deficient N-heterocycles (isoquinoline, quinolines, and quinoxalines) and methylbenzenes leading to regiospecific C–aroylation has been accomplished using AlCl3 as the catalyst in the presence of oxidant TBHP. This protocol is a practical alternative to the classical Minisci reaction.

  在存在氧化剂TBHP的情况下，使用AlCl 3作为催化剂，可实现缺电子的N-杂环（异喹啉，喹啉和喹喔啉）与甲基苯之间的区域选择性交叉脱氢偶联，从而导致区域特异性的C-芳基化。该协议是经典Minisci反应的一种实用替代方案。

  A general and metal-free visible-light-induced decarboxylative arylation procedure at room temperature was described for the construction of acylated heterocyclic derivatives, such as benzimidazo/indolo[2,1-a]isoquinolin-6(5H)-ones, aroylazaspiro[4.5]trienones, thioflavones, and so on. This practical arylation procedure was conducted by using 2,4,5,6-tetra(9H-carbazol-9-yl)isophthalonitrile (4CzIPN)

  描述了一种在室温下通用且无金属的可见光诱导的脱羧芳基化方法，用于构建酰化杂环衍生物，例如苯并咪唑/吲哚并[ 2,1 - a ]异喹啉-6（5 H）-ones，芳酰基azaspiro [4.5]三烯酮，硫代黄酮等。通过在温和的条件下使用2,4,5,6-四（9 H-咔唑-9-基）间苯二甲腈（4CzIPN）作为光催化剂来进行该实用的芳基化步骤，避免了使用额外的碱，传统的加热，和金属试剂。
