Photo/electrocatalytic site-selective C-H functionalization of 8-aminoquinolines and their analogues

8-Aminoquinolines and their analogues are important nitrogenous compounds that are widely used in organic chemistry, medicinal chemistry, material science and other fields. In recent years, the synthesis of functional 8-aminoquinolines and their analogues has become a research hotspot for organic and pharmaceutical chemists, and great progress has been made. Photo/electrochemistry-induced C-H functionalization provides a new concept for modern synthetic chemistry, which is greener, more atom- and step-economic. Therefore, as a green and efficient synthetic strategy, photo/electrocatalysis can be used for the selective C-H functionalization of 8-aminoquinolines and their analogues. In this study, 8-aminoquinoline, 8-hydroxyquinoline, and 1-naphthylamine scaffolds are classified, and the constructions of their selective C-H activation systems are reviewed in terms of photocatalytic and electrocatalytic synthesis. Finally, an outlook for the future of this field is summerized. In this review, 8-aminoquinoline, 8-hydroxyquinoline, and 1-naphthylamine scaffolds are classified, and the constructions of their selective C-H activation systems are reviewed in terms of photocatalytic and electrocatalytic synthesis.
