Shen, Jiabin published the artcileSelective Mono- and Diamination of Ketones in a Combined Copper-Organocatalyst System, Recommanded Product: 3-Acetylthiophene, the main research area is pyrazole ketone chemoselective preparation; ketone azole copper organocatalyst mono amination; dipyrazole ketone chemoselective preparation; azole ketone copper organocatalyst di amination.
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.
Organic Letters published new progress about Amination (chemoselective). 1468-83-3 belongs to class benzothiophene, name is 3-Acetylthiophene, and the molecular formula is C6H6OS, Recommanded Product: 3-Acetylthiophene.
