A copper-catalyzed three-component annulation for the synthesis of functionalized 2-quinolones was developed. Three reactions including an SN2, a Knoevenagel, and finally C-N bond formation are involved in the designed cascade reaction using 2-bromoacylarenes, 2-iodoacetamide, and nucleophiles as the three components. A new catalytic system was discovered during the study and this modular approach is highly efficient to access functionalized 2-quinolone derivatives, compatible with a broad range of functional groups, scalable, and step-economic. Further derivatization of the obtained product demonstrates the synthetic utility of this method. In addition to this study using 2-Bromonicotinaldehyde, there are many other studies that have used 2-Bromonicotinaldehyde(cas: 128071-75-0Formula: C6H4BrNO) was used in this study.
2-Bromonicotinaldehyde(cas: 128071-75-0) belongs to pyridine. Pyridine and pyridine-derived structures are privileged pharmacophores in medicinal chemistry and an essential functionality for organic chemists. As the prototypical π-deficient heterocycle, pyridine illustrates distinctive chemistry as both substrate and reagent. Formula: C6H4BrNO
