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.
Gold(I)-Catalyzed Cascade Approach for the Synthesis of Tryptamine-Based Polycyclic Privileged Scaffolds as α<sub>1</sub>-Adrenergic Receptor Antagonists
An efficient and facile gold(I)-catalyzed one-pot cascade protocol has been developed for the synthesis of tryptamine-fused polycyclic privileged structures through the treatment of substituted tryptamines and 2-ethynylbenzoic acids or 2-ethynylphenylacetic acids. This strategy features the formation of one C-C bond and two C-N bonds with high yields and broad substrate tolerance. The selected reduced target molecules are validated to perform as alpha(1)-adrenergic receptors antagonists. The most potent one, 4bh, exhibits an IC50 value of 277 nM on alpha(1A) subtype with a selectivity ratio of 15.8 over alpha(1B) subtype.
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
