  通过氧化卤代硼化对 N-芳基酰胺和脲进行区域选择性邻位卤化：利用硼反应性实现高效的 C-卤键安装

  摘要：

  在N-芳基酰胺和脲的邻位安装 C-卤素键代表了一种制备生物活性化合物中普遍存在的基序的工具。为了构建这种普遍的债券，大多数方法都需要使用贵金属和多步骤过程。在这里，我们报告了一种新的方案，用于解决使用氧化卤代硼化对N-芳基酰胺和脲进行区域选择性邻位卤化的长期挑战。通过利用硼对氮的反应性，我们将羰基定向硼化与连续卤代硼化结合起来，从而能够在N-芳基酰胺和脲所需的邻位精确引入 C-X 键。该方法为在温和条件下合成卤化N-杂芳烃提供了一种高效、实用且可扩展的解决方案，突出了硼反应性在指导反应区域选择性方面的优越性。

• Continuous Recycling of Homogeneous Pd/Cu Catalysts for Cross-Coupling Reactions
  作者：Siddharth Sharma、K. C. Basavaraju、Ajay K. Singh、Dong-Pyo Kim

  DOI：10.1021/ol501802w

  日期：2014.8.1

  Given the importance of homogeneous catalysts recycling in organic chemistry, we have developed a unique microfluidic loop system for automated continuous recirculation of a soluble polymer supported metal catalyst for novel isocyanide cross-coupling reactions under thermomorphic multicomponent solvent (TMS) conditions. Our system provides an innovative approach for the chemical library synthesis of quinazolinone derivatives as well as an important intermediate of Merck's LTD4 antagonist "Singulair" with efficient continuous homogeneous catalyst recycling.
• Ligand-free palladium assisted insertion of isocyanides to urea derivatives for cascade synthesis of phenylamino-substituted quinazolinones
  作者：Siddharth Sharma、Abhilasha Jain

  日期：2014.10

  Palladium catalyzed cascade coupling of substituted urea derivatives and tert-butyl isocyanide for the efficient synthesis of phenylamino-substituted quinazolinones has been developed in moderate to good yields. This method provides a short and alternative approach for the synthesis of quinazolinones derivatives which are valuable compounds with biological and pharmacological potentials. A plausible mechanistic scheme is proposed. (C) 2014 Elsevier Ltd. All rights reserved.

  A new, efficient and practical synthesis of quinazolin-4(3H)-ones is reported via molybdenum-mediated cyclocarbonylation using microwave irradiation. These methods allow access to a wide range of quinazolin-4(314)-ones in reasonable yields without the need for gaseous carbon monoxide and palladium catalysts. A range of reactions illustrating the wide scope of this chemistry was carried out and all proceeded in reasonable yields. (C) 2011 Elsevier Ltd. All rights reserved.
