  versatile 3-acylindoles through Rh(III)-catalyzed C–H activation and annulation cascade of N-phenylamidines with α-Cl ketones was developed, in which α-Cl ketones serve as unusual one-carbon (sp3) synthons. This strategy features high regioselectivity, efficiency, wide substrate tolerance, and mild reaction conditions, which further underscore its synthetic utility in drug molecule synthesis.

  在本研究中，开发了一种新的合成策略，可通过Rh（III）催化的C–H活化和N-苯基am与α-Cl酮的环合级联反应直接生产通用的3-acylindoles ，其中α-Cl酮用作不寻常的一碳（sp 3）合成子。该策略具有较高的区域选择性，效率，宽的底物耐受性和温和的反应条件，这进一步强调了其在药物分子合成中的合成效用。
• Nucleophilic Addition of Grignard Reagents to 3–Acylindoles: Stereoselective Synthesis of Highly Substituted Indoline Scaffolds

  3-Acylindoles undergo nucleophilic-type reactions with Grignard reagents to efficiently afford either cis- or trans-substituted indolines, depending on the different quenching procedures. The enolate intermediate could be trapped by aryl acyl chlorides to provide indolines bearing a quaternary carbon center with high stereoselectivity. In contrast, the use of benzyl bromide as an electrophile results

  3-Acylindoles与Grignard试剂进行亲核型反应，可有效提供顺式或反式取代的二氢吲哚，具体取决于不同的淬灭步骤。烯醇化物中间体可以被芳基酰氯捕获，以提供具有高立体选择性的带有季碳中心的二氢吲哚。相反，使用苄基溴作为亲电试剂会导致吲哚环断裂。通过用一锅法用DDQ氧化可将二氢吲哚产物轻松转化为吲哚。

  A novel palladium-catalyzed carbonylation of indoles with CO and aromatic boronic acids for the synthesis of indol-3-yl aryl ketones was developed. The reaction tolerates a wide range of functional groups and gives a variety of valuable indol-3-yl aryl ketones in high yields under mild conditions.

  [reaction: see text] Syntheses of 2-aryl and 2,3-substituted indoles were realized by modified double elimination protocol. Under basic conditions, vinyl sulfones derived from the reaction of 2-aminobenzyl sulfone with benzaldehydes underwent cyclization and alkylation followed by elimination of sulfinic acid to afford 2,3-substituted indoles.

  [反应：见正文]通过改良的双消除方案实现了2-芳基和2,3-取代的吲哚的合成。在碱性条件下，使2-氨基苄基砜与苯甲醛反应衍生的乙烯基砜进行环化和烷基化，然后消除亚磺酸，得到2,3-取代的吲哚。

  A new robust transition‐metal‐free method for synthesis of 1,2‐disubstituted indoles from easily available tertiary amides is presented. This approach can be performed in a one‐pot two‐step manner directly from secondary amines. Mechanistic studies showed that acyl transfer might be an important step in the course of the reaction. Viability of the presented approach for benzofurans and benzothiophenes

  提出了一种新的耐用的无过渡金属的方法，由易于获得的叔酰胺合成1,2-二取代的吲哚。该方法可以直接从仲胺以一锅两步的方式进行。机理研究表明，酰基转移可能是反应过程中的重要一步。还证明了所提出的方法对于苯并呋喃和苯并噻吩合成的可行性。
