  • Palladium-Catalyzed Decarboxylative Couplings of 2-(2-Azaaryl)acetates with Aryl Halides and Triflates
    作者:Rui Shang、Zhi-Wei Yang、Yan Wang、Song-Lin Zhang、Lei Liu
    DOI:10.1021/ja107103b
    日期:2010.10.20
    Pd-catalyzed decarboxylative cross-couplings of 2-(2-azaaryl)acetates with aryl halides and triflates have been discovered. This reaction is potentially useful for the synthesis of some functionalized pyridines, quinolines, pyrazines, benzoxazoles, and benzothiazoles. Theoretical analysis shows that the nitrogen atom at the 2-position of the heteroaromatics directly coordinates to Pd(II) in the decarboxylation
    已发现 Pd 催化的 2-(2-氮杂芳基) 乙酸酯与芳基卤化物和三氟甲磺酸酯的脱羧交叉偶联。该反应可用于合成一些官能化的吡啶、喹啉、吡嗪、苯并恶唑和苯并噻唑。理论分析表明,杂芳烃 2 位的氮原子直接与脱羧过渡态的 Pd(II) 配位。
  • Elemental Sulfur-Promoted Oxidative Rearranging Coupling between o-Aminophenols and Ketones: A Synthesis of 2-Alkyl benzoxazoles under Mild Conditions
    作者:Thanh Binh Nguyen、Pascal Retailleau
    DOI:10.1021/acs.orglett.7b01775
    日期:2017.7.21
    In the presence of N-methylpiperidine, elemental sulfur was found to act as excellent oxidant in promoting oxidative rearranging coupling between o-aminophenols and ketones. A wide range of 2-alkylbenzoxazoles was obtained under mild conditions.
    在N-甲基哌啶的存在下,发现元素硫在促进邻氨基酚与酮之间的氧化重排偶联中起极好的氧化剂的作用。在温和的条件下获得了广泛的2-烷基苯并恶唑。
  • Microwave-Assisted Direct Synthesis of 2-Substituted Benzoxazoles from Carboxylic Acids under Catalyst and Solvent-Free Conditions
    作者:Asit K. Chakraborti、Raj Kumar、C. Selvam、Gurmeet Kaur
    DOI:10.1055/s-2005-868509
    日期:——
    A direct coupling of carboxylic acids with 2-aminophenol under microwave irradiation has been achieved leading to the synthesis of 2-substituted benzoxazoles under metal and solvent-free conditions. Aliphatic, aromatic and heteroaromatic carboxylic acids provide good yields. Benzoxazole formation takes place in the presence of chloro, methoxy, phenoxy, thiophenoxy, and α,β-unsaturated functionalities. In the case of dicarboxylic acids, the reaction proceeds via the formation of the corresponding anhydride with predominant formation of the mono-benzoxazole.
    在微波辐射下,羧酸与2-氨基苯酚直接耦合,实现了无金属和溶剂条件下的2-取代苯并恶唑合成。脂肪族、芳香族和杂芳香族羧酸均可提供良好的产率。苯并恶唑的形成在氯、甲氧基、苯氧基、噻吩氧基和α,β-不饱和功能团的存在下发生。对于二元羧酸,反应通过形成相应的酸酐进行,主要生成单苯并恶唑。
  • One-Pot Synthesis of 2-Substituted Benzoxazoles Directly from Carboxylic Acids
    作者:Dinesh Kumar、Santosh Rudrawar、Asit K. Chakraborti
    DOI:10.1071/ch08193
    日期:——
    Methanesulfonic acid has been found to be a highly effective catalyst for a convenient and one-pot synthesis of 2-substituted benzoxazoles by the reaction of 2-aminophenol with acid chlorides, generated in situ from carboxylic acids. Aryl, heteroaryl, and arylalkyl carboxylic acids provided excellent yields of the corresponding benzoxazoles. The reaction conditions were compatible with various substituents
    已发现甲磺酸是一种高效的催化剂,可通过 2-氨基苯酚与由羧酸原位生成的酰氯反应方便地一锅合成 2-取代的苯并恶唑。芳基、杂芳基和芳烷基羧酸提供了相应苯并恶唑的优异产率。反应条件与各种取代基如氯、溴、硝基、甲氧基、环戊氧基、苯氧基、噻吩氧基和共轭双键相容。发现苯并恶唑的形成通常与取代的 2-氨基苯酚有关。
  • Synthesis of 2-benzyl benzoxazoles and benzothiazoles <i>via</i> elemental sulfur promoted cyclization of styrenes with 2-nitrophenols and <i>N</i>,<i>N</i>-dialkyl-3-nitroanilines
