pyrrolo/pyrido[2,1-a][1,3]benzoxazinones and pyrrolo/pyrido[2,1-a]quinazolinones from 2-amino benzoic acids and 2-amino benzamides via a gold(I)-catalyzedtandemcoupling/cyclization process. The tricyclic or polycyclic molecular architectures were constructed in one pot with the formation of three new bonds.
我们已经开发了一种简单的方法,可通过2-氨基苯甲酸和2-氨基苯甲酰胺合成吡咯并/吡啶并[ 2,1- a ] [1,3]苯并恶嗪酮和吡咯并/吡啶并[ 2,1- a ]喹唑啉酮金(I)催化的串联偶联/环化过程。一环构建了三环或多环分子结构,形成了三个新的键。
Gold‐catalyzed Rapid Construction of Nitrogen‐containing Heterocyclic Compound Library with Scaffold Diversity and Molecular Complexity
react with alkynoic acids (AAs) to achieve gold‐catalyzed highly selective cascade reactions to furnish novel indole‐fused skeletons. Furthermore, with this powerful gold catalytic system, a library of indole/pyrrole/thiophene/benzene/naphthalene/pyridine‐based nitrogen‐containing heterocyclic compounds (NCHCs) with scaffold diversity and molecular complexity was constructed rapidly using various amine
scope. In addition, this is the first example of the generation of an indole/thiophene/pyrrole/pyridine/naphthalene/benzene-fused N-heterocycle library through gold catalysis in water from readily available materials. Notably, the discovery of antibacterial molecules from this library demonstrates its high quality and potential for the identification of active pharmaceutical ingredients.
