  通过Rh催化的新型多角色导向基团的选择性转化进行面向多样性的合成。

  摘要：

  在过渡金属催化的CH功能化的背景下，开发了导向基团策略以提高化学反应性和选择性。最近，为了避免传统的单角色导向基团的固有局限性，开发了一种双角色氧化导向基团策略，其中导向基团既充当导向基团又充当氧化剂。在本文中，我们报道了一个多角色导向基团，该基团具有多个反应位点，表现出独特的反应性和选择性，并通过铑催化的CH活化/炔烃环化反应从一种起始原料生成四种不同类型的产物。通过调节溶剂和氧化剂，可以很好地控制出色的产品多样性以及区域和氧化还原选择性。

  synthesis of isoquinolones from benzamides and alkynes via the oxidative ortho C−H activation of benzamides has been developed. Ag2CO3 proved to be an optimal oxidant when MeCN was used as a solvent, and [RhCp*Cl2]2 was utilized as an efficient catalyst. Both N-alkyl and N-aryl secondary benzamides can be applied as effective substrates. Furthermore, primary benzamides react with two alkyne units, leading

  已开发出一种方法，可通过苯甲酰胺的氧化邻位C-H活化从苯甲酰胺和炔烃高产且轻松地合成异喹诺酮。当以MeCN为溶剂和[RhCp * Cl 2 ] 2时，Ag 2 CO 3被证明是最佳氧化剂。被用作有效的催化剂。N-烷基和N-芳基仲苯甲酰胺都可以用作有效的底物。此外，一级苯甲酰胺与两个炔烃单元反应，通过双重CH活化和氧化偶合生成三环产物。还证明了与结构相关的1-羟基异喹啉的反应性，其中可以同时生成含N和O的rhodocyclic中间体，从而导致构建不同的含O或N的杂环。

  Pd/C-catalyzed direct synthesis of N-aryl and N-alkyl isoquinolones was developed via the annulation reactions of benzamides and alkynes in high yields (up to 99%) through the cleavage of CH/NH bonds. The reaction was ligand-free and air was used as oxidant. High regioselectivities were found when unsymmetrical alkynes or meta-benzamides were used as substrates. The heterocyclic carboxamide substrates

  通过苯甲酰胺和炔烃的环化反应，通过C H / N H键的裂解，Pd / C催化直接合成N-芳基和N-烷基异喹诺酮。该反应不含配体，将空气用作氧化剂。当使用不对称炔烃或间苯甲酰胺作为底物时，具有较高的区域选择性。杂环羧酰胺底物，例如呋喃和噻吩衍生物，也以高收率提供了相应的产物。
• Ruthenium-Catalyzed Synthesis of Isoquinolones with 8-Aminoquinoline as a Bidentate Directing Group in C–H Functionalization

  Ruthenium-catalyzed oxidative annulation of N-quinolin-8-yl-benzamides with alkynes in open air has been achieved using 8-aminoquinolinyl moiety as a bidentate directing group in the presence of Cu(OAc)(2)center dot H2O as an oxidant. This reaction offers a broad substrate scope, and both symmetrical and unsymmetrical alkynes can be applied. High regioselectivity was achieved in the case of unsymmetrical (aryl)alkynes. Reaction with heteroaryl amides was also successful in this catalytic process. A ruthenium-N-quinolin-8-yl-benzamide complex was isolated in the absence of alkyne; in the absence of both N-quinolin-8-yl-benzamide and alkyne, in contrast to literature, only the monoacetate complex RuCl(OAc)(p-cymene), but not the bis-acetate complex Ru(OAc)2(p-cymene), was isolated. These data suggest that this reaction may proceed via N,N-bidentate chelate complex. Key products were characterized by X-ray crystallography.
