  Sulfoximine Directed Intermolecular o-C–H Amidation of Arenes with Sulfonyl Azides

  摘要：

  The Ru(II)-catalyzed Intermolecular o-C-H amidation of arenes in N-benzoylated sulfoximine with sulfonyl azides is demonstrated. The reaction proceeds with broad substrate scope and tolerates various functional groups. Base hydrolysis of the amidation product provides the anthranilic acid derivatives and methylphenyl sulfoximine (MPS) directing group. This method Is successfully employed for the synthesis of HMR 1766.

• Direct CH Amidation of Benzoic Acids to Introduce<i>meta</i>- and<i>para</i>-Amino Groups by Tandem Decarboxylation
  作者：Donggun Lee、Sukbok Chang

  DOI：10.1002/chem.201500331

  日期：2015.3.27

  The Ir‐catalyzed mild CH amidation of benzoic acids with sulfonyl azides was developed to give reactions with high efficiency and functional‐group compatibility. Subsequent protodecarboxylation of ortho‐amidated benzoic acid products afforded meta‐ or para‐substituted (N‐sulfonyl)aniline derivatives, the latter being inaccessible by other CH functionalization approaches. The decarboxylation step

  开发了具有磺酰叠氮化物的苯甲酸的Ir催化轻度CH酰胺化反应，可实现高效且具有官能团相容性的反应。随后，将氨基酰胺化的邻氨基苯甲酸产物进行原羧化反应，可得到间位或对位取代的（N-磺酰基）苯胺衍生物，而其他CH官能化方法则无法获得后者。脱羧步骤与酰胺化条件兼容，可实现方便的一锅两步工艺。

  Added at the eleventh hour: A method for the late-stage directed amination of benzoic acids is presented. It allows rapid access to both small amino-functionalized analogues and large conjugates, including PROTACs, peptide conjugates and probes for chemical biology. Selection of the right catalyst and reagent enabled the use of high-throughput experimentation and automation.

  excellent yields up to 99% and with complete chemoselectivity. The mechanism is suggested to involve cop- per(II)-mediated dehydration of the homoallylic amino alcohol. Protonation of the resultant cop- per(II)-activated aminodiene is then thought to trigger subsequent intramolecular hydroamination to give the partially hydrogenated nitrogen heterocycle.

  描述了一种新的高效合成路线，该路线依赖于温和且操作简便的条件下，三氟甲磺酸铜（II）催化均烯丙基氨基醇分子内胺化，生成反式-2,5-二氢-1 H-吡咯和1,2-二氢喹啉。对于反应导致的反式-2,5-二氢-1- ħ -吡咯产物，的52-83％的产率与沿反式选择性高达> 99：1个博士和EE值高达97％是从对映体富集完成1-（甲苯磺酰氨基）戊-4-烯-2-醇，ee范围为91–99％。不需要惰性和无湿气的条件，涉及1- [2-（甲苯磺酰基氨基）苯基] but-3-en-1-ols的反应可提供相应的1,2-二氢喹啉产物，收率高达99％，且完全的化学选择性。建议该机制涉及铜（II）介导的均烯丙基氨基醇的脱水。然后认为所得的经铜（II）活化的氨基二烯的质子化会触发随后的分子内加氢胺化反应，从而产生部分氢化的氮杂环。

  cycloisomerization of 1-(2-aminophenyl)prop-2-yn-1-ols is described. The reaction is operationally straightforward and accomplished in good to excellent yields (48–91%) from a wide range of alcohol substrates that are low cost, easily accessible, and ecologically benign. The utility of the approach as a potential scale-up strategy for the synthesis of the indole was exemplified by the large-scale synthesis of one
