  日期：2013.7.29

  New horizons in the utility of azides: The rhodium‐catalyzed intermolecular direct CH amination of arenes with alkyl azides provides a convenient route to N‐alkyl anilines (see scheme; DG=directing group). Alkyl azides with a wide range of functional groups reacted readily with various substrates, including benzamides, aromatic ketones, and flavones.

  叠氮化物应用的新视野：用烷基叠氮化物进行铑催化的芳烃分子间直接CH胺化反应可提供一条通往N烷基苯胺的便捷途径（参见方案； DG =导向基团）。具有多种官能团的烷基叠氮化物易于与各种底物反应，包括苯甲酰胺，芳族酮和黄酮。

• Synthetic approach to flavanones and flavones via ligand-free palladium(ii)-catalyzed conjugate addition of arylboronic acids to chromones
  作者：Donghee Kim、Kyungrok Ham、Sungwoo Hong

  DOI：10.1039/c2ob26061a

  日期：——

  The remarkable catalytic effects of Fe(OTf)3 in the context of the Pd(II)-catalyzed conjugate addition of arylboronic acids to chromones were observed to yield a variety of flavanones under mild conditions. The addition of catalytic amounts of DDQ and KNO2 to the reactions exclusively yielded flavone analogs. The reaction scope for the transformation was fairly broad, affording good yields of a wide range of flavanones and flavones, which are privileged structures in many biologically active compounds.

  在Pd(II)催化的芳基硼酸与色酮的共轭加成反应中，Fe(OTf)3显示出了显著的催化效应，能够在温和条件下合成各种黄酮。向反应中添加催化量的DDQ和KNO2则专门产生黄酮类似物。该转化的反应范围相当广泛，提供了良好的收率，合成了多种黄酮和黄酮类化合物，这些化合物在许多生物活性化合物中是具优势的结构。
• Palladium-Catalyzed Dehydrogenation/Oxidative Cross-Coupling Sequence of β-Heteroatom-Substituted Ketones

  DOI：10.1002/anie.201206610

  日期：2012.11.5

  Concise and selective: The title one‐pot sequence allows formation of the enone functionality and subsequent cross‐coupling. The process provides access to highly functionalized cyclic enolones and enaminones from readily accessible β‐heteroatom‐substituted cyclic ketones.
