  Palladium mediated synthesis of isoindolinones and isoquinolinones

  摘要：

  The palladium-catalyzed reactions of 2-iodo-N-substituted benzamides 5-10 with acrylic esters 11-14 led to N-substituted-3-alkylisoindolinone esters 15-22 in good yields. The esters of isoindolinones 15-22 underwent hydrolysis reactions yielding the N-aryl-1,2,3,4-tetrahydro-1-oxoisoquinoline-3-carboxylic acid 26-31 in good yields. (c) 2005 Elsevier Ltd.

• Divergent Reactivity of 1,2,3-Benzotriazin-4(3<i>H</i>)-ones: Photocatalytic Synthesis of 3-Substituted Isoindolinones Achieved through a Nitrogen-Mediated Hydrogen Atom Shift

  regioselective visible-light-mediated denitrogenative alkene insertion of 1,2,3-benzotriazin-4(3H)-ones was developed to access 3-substituted isoindolinones, an important structural motif present in many biologically active molecules and natural products. Notably, divergent reactivity was achieved by switching from reported nickel catalysis (where C3-substituted 3,4-dihydroisoquinolin-1(2H)-ones form) to

  开发了一种区域选择性可见光介导的 1,2,3-苯并三嗪-4(3 H )-酮的脱氮烯烃插入，以获取 3-取代异吲哚啉酮，这是许多生物活性分子和天然产物中存在的重要结构基序。值得注意的是，通过从报道的镍催化（其中形成 C3 取代的 3,4-二氢异喹啉-1(2 H )-酮）转向光催化，实现了不同的反应性，其中光催化脱氮和随后的氮介导的氢原子转移导致排他性3-取代异吲哚啉酮形成。所开发的光催化反应与活化的末端烯烃和环状α,β-不饱和酯和酮相容，对1,2,3-苯并三嗪-4(3 H )-酮的N-取代具有广泛的官能团耐受性。该过程的实用性通过克级合成和合成后酰胺化得以凸显。为了了解这种独特的产物选择性的起源，进行了实验和计算机制研究。

  proceeds through NHC-catalyzed tandem imine umpolung–intramolecular aza-Michael addition followed by oxidation, while molecular oxygen in air acts as a sole oxidant. Atom efficiency, operational simplicity, large-scale syntheses, and mild reaction conditions are the salient features of this method. Mechanistic studies were indicative of the necessity of molecular oxygen in air as oxidant for the conversion

  Rh(III)-catalyzed oxidative coupling reactions between benzamides or heteroaryl carboxamides and olefins have been developed. The vinylation product can further undergo a Michael reaction leading to gamma-lactam in the case of electron-withdrawing olefins.
