Jalani, Hitesh B.,Venkateswararao, Eeda,Manickam, Manoj,Jung, Sang-Hun
supporting information, p. 1966 - 1970 (2016/12/16)
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
Synthesis, antibacterial activity and binding mode analysis of some novel 1,4-diaryl imidazole thiones
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
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.

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
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
