I found the field of Chemistry very interesting. Saw the article Merging photoredox catalysis with transition metal catalysis: Direct C4-H amination of 8-hydroxyquinoline derivatives published in 2019. Product Details of 67-51-6, Reprint Addresses Yang, F; Wu, YJ (corresponding author), Zhengzhou Univ, Key Lab Appl Chem Henan Univ, Henan Key Lab Chem Biol & Organ, Coll Chem & Mol Engn, Zhengzhou 450052, Henan, Peoples R China.; Wu, YS (corresponding author), TetranovBiophann LLC, Zhengzhou 450001, Henan, Peoples R China.; Wu, YS (corresponding author), Collaborat Innovat Ctr New Drug Res & Safety Eval, Zhengzhou 450001, Henan, Peoples R China.. The CAS is 67-51-6. Through research, I have a further understanding and discovery of 3,5-Dimethyl-1H-pyrazole
A practical and efficient protocol for Ag/Ru-cocatalyzed regioselective C-H amination of 8-hydroxyquinoline esters with pyrazoles was developed, This reaction proceeded smoothly via a photoredox-mediated direct C-H/N-H oxidative coupling process. The remarkable features of this reaction include the wide substrate scope, mild reaction conditions and high regioselectivity at the C4 site of the quinolinyl moiety. (C) 2019 Elsevier Ltd.
