  Transition-metal-catalyzed oxidative C-H cyclization of anilines has been an attractive and powerful strategy for the efficient construction of N-heterocycles. However, the primary and tertiary anilines are rarely employed in this strategy due to the relatively unstability with strong oxidants or the presence of three C-N bonds. By using aerobic oxidative protocol, we describe here a novel Rh-catalyzed

  苯胺的过渡金属催化的氧化 CH 环化已成为有效构建 N-杂环的有吸引力且有效的策略。然而，由于与强氧化剂相对不稳定或存在三个CN键，伯苯胺和叔苯胺很少用于该策略。通过使用有氧氧化协议，我们在这里描述了一种新颖的 Rh 催化 CH 环化各种苯胺与炔烃和 CO。特别是，简单的伯苯胺和通过 CN 键裂解容易制备的叔苯胺可以很容易地转化为 quinolin-2 (1H)-ones，它们是高附加值、具有生物学意义的 N-杂环化合物。
• Rh-Catalyzed Construction of Quinolin-2(1<i>H</i>)-ones via C–H Bond Activation of Simple Anilines with CO and Alkynes

  A novel and efficient Rh-catalyzed Carbonylation and annulation of simple anilines with CO and alkynes through N-H and CH bond activation for the direct synthesis of quinolin-2(1H)-ones has been developed. Simple anilines without preactivation, broad substrate scope with hetero/polycycles, and high-value products make this protocol very-practical and attractive. A key rhodacycle complex was isolated and well-characterized.
• Iridium-Catalyzed Annulation of <i>N</i>-Arylcarbamoyl Chlorides with Internal Alkynes

  日期：2010.7.21

  An iridium complex successfully catalyzed the annulation of various N-arylcarbamoyl chlorides with internal alkynes to afford 2-quinolones in good to excellent yields. The present reaction is widely applicable to substrates with various functionalities. An amide-iridacycle complex was isolated, and it is likely that such an iridacycle species is a key intermediate in the catalytic reaction.

  Combined experimental and theoretical investigations into the phenyliodine bis(trifluoroacetate) (PIFA)-mediated reaction of N-arylcinnamamide to produce 3-arylquinolin-2-one derivatives have been conducted. High regioselectivity during the aryl migration process was observed in 3,3-disubstituted acrylamides. Density functional theory calculation was conducted in an attempt to understand the mechanism
