  A Transition Metal-Free Minisci Reaction: Acylation of Isoquinolines, Quinolines, and Quinoxaline

  摘要：

  Transition metal-free acylation of isoquinoline, quinoline, and quinoxaline derivatives has been developed employing a cross dehydrogenative coupling (CDC) reaction with aldehydes using substoichiometric amount of TBAB (tetrabutylammonium bromide, 30 mol %) and K2S2O8 as an oxidant. This intermolecular acylation of electron-deficient heteroarenes provides an easy access and a novel acylation method of heterocyclic compounds. The application of this CDC strategy for acylation strategy has been illustrated in synthesizing isoquinoline-derived natural products.

• Radical C−H Acylation of Nitrogen Heterocycles Induced by an Aerobic Oxidation of Aldehydes
  作者：Subhasis Paul、Manotosh Bhakat、Joyram Guin

  DOI：10.1002/asia.201900857

  日期：2019.9.16

  ketones is described herein. The reaction involves cross-dehydrogenative coupling between aldehydes and heteroaromatic bases with molecular oxygen (O2 ). The key aspect of the method is the generation of reactive acyl radical via homolytic activation of aldehyde C-H bond using O2 as the sole oxidant. The reaction has a good substrate scope with respect to aldehydes and functionalized nitrogen heterocycles

  本文描述了用于合成不对称杂芳基酮的需氧自由基方法。该反应涉及醛和杂芳族碱与分子氧（O2）之间的交叉脱氢偶联。该方法的关键方面是使用O2作为唯一氧化剂，通过醛CH键的均质活化来生成反应性酰基基团。关于醛和官能化的氮杂环，该反应具有良好的底物范围。根据我们的机理研究，建议该反应采用自由基链途径。该方法的合成应用在天然生物碱（±）安格西汀的形式合成中得到了证明。
• Transition metal-free Minisci reaction promoted by NCS, and TBHP: acylation of heteroarenes

  日期：2016.2

  A method for acylation for heteroarenes under metal-free conditions has been described using NCS as an additive and TBHP as an oxidant. This method has been successfully employed in acylation of a variety of aldehyde with heteroarenes. The application of the method has been illustrated in synthesizing isoquinoline derived natural products. This strategy provides an efficient, mild and inexpensive method for acylation of heteroarenes. (C) 2015 Elsevier Ltd. All rights reserved.
