One-Pot Synthesis of 1,2,4,5-Tetrasubstituted Imidazoles in Ionic Liquid
摘要:
The four‐component condensation of benzil, aromatic aldehyde, primary amine, and ammonium acetate catalyzed by TFA in ionic liquid [Bpy]BF4 at 80°C provided 1,2,4,5‐tetrasubstituted imidazoles in moderate to high yields.
Tetrasubstituted imidazoles were synthesized in high yields via the four-component reaction of aromatic aldehydes, amines, substituted benzils and ammonium acetate catalyzed by a porous CeO2 nanorod. Their anti-cancer activities on the Huh-7 hepatocellular carcinoma cell and antibacterial activities on four bacterial species (wild-type Escherichia coli, wild-type Staphylococcus aureus, Pseudomonas
