Shen, Jiabin;Wang, Zhihao;Zhang, Yuru;Xu, Jun;Liu, Xiaogang;Shen, Chao;Zhang, Pengfei research published 《 Selective Mono- and Diamination of Ketones in a Combined Copper-Organocatalyst System》, the research content is summarized as follows. Herein, a simple and mild protocol for syntheses of α-pyrazoles I [R = 4-Me, 5-I, 3-Ph, etc.; Ar = Ph, 3-MeC6H4, 4-ClC6H4, etc.] and α,α-dipyrazole ketone derivatives II [R2 = R3 = H, 4-Cl, 4-Br, etc.; Ar1 = Ph, 3-FC6H4, 4-ClC6H4, etc.] via combined copper-organocatalyzed chemoselective mono- and diamination of ketones using azoles as amine source were reported. Various substrates were compatible and provided the corresponding products I and II in moderate to good yields.
