An efficient, practical, straight forward, and transition metal-free three-component synthesis of diversely substituted imidazoles and 2H-imidazolones from β-ketoamines, acylating agents, and ammonium acetate has been described herein. This approach invol
Synthesis, Characterization, and Antibacterial Activity of Some Novel Substituted Imidazole Derivatives via One-pot Three-Component
Ramagiri, Raj Kumar,Thupurani, Murali Krishna,Vedula, Rajeswar Rao
, p. 1713 - 1717 (2015/11/09)
A simple and highly efficient one-pot, three-component synthesis of novel substituted imidazole derivatives has been reported by the reaction of 3-(2-bromoacetyl)-2H-chromen-2-one, ammonium thiocyanate, and phenacyl aniline in the presence of acetic acid

Ganguly, Swastika,Singh, Nalini,Upadhyay, Arpita
, p. 419 - 424 (2019/01/21)
A novel series of fifteen diaryl imidazole thiones 2a-o was synthesized by reacting the corresponding 1-(aryl)-2-(arylamino)-ethanones 1 with ammonium thiocyanate. The compounds have been characterized on the basis of elemental analysis and spectral data.

1,8-Diazabicyclo[5.4.0]undec-7ene (DBU) facilitated the oxidative cyclization of phenacyl amide in the presence of atmospheric oxygen under environmentally friendly conditions. The reaction has been studied under various conditions and a plausible mechani
PREPARATION OF NEW THIOHYDROXAMIC ACID DERIVATIVES: SYNTHESIS OF SUBSTITUTED 1-HYDROXY-1,2-DIHYDROIMIDAZOLE-2-THIONES

, p. 793 - 806 (2007/10/02)
A general method for the synthesis of the title compounds is reported.The N-phenacylarylamines (11), prepared from the corresponding phenacyl bromides (9) and arylamines (10), give the thiono (or dithio) carbamates (12) on treatment with phenoxythionocarb
Hypervalent iodine mediated syntheses of heterocycles: One-pot facile syntheses of 1,4-diaryl-2-mercaptoimidazoles, 2-(α-anilinoacetyl)thiophenes and 1-aryl-2-mercapto-4-(2-thienyl)imidazoles from aryl/2-thienyl methyl ketones

Successive treatment of acetophenones (1a-e) or 2-acetylthiophene (4) with benzene, appropriate aniline and KSCN/AcOH leads to the formation of 1,4-diaryl-2-mercaptoimidazoles (3aa-3ea) or 1-aryl-2-mercapto-4-(2-thienyl)imidazoles (6a-f) respectively.This procedure also provides 2(α-anilinoacetyl)thiophenes (5a-f) in one pot from 4.
Nucleophilic Substitution Reactions of Phenacyl Benzenesulphonates with Anilines in Methanol-Acetonitrile Mixtures
Lee, Ikchoon,Shim, Chang Sub,Chung, Soo Young,Lee, Hai Whang
, p. 975 - 982 (2007/10/02)
The nucleophilic substitution reactions of phenacyl benzenesulphonates with anilines in methanol-acetonitrile have been studied.A stronger nucleophile was found to cause less bond cleavage, while a better leaving group led to less bond formation, in compl
