A three-step synthesis of 1-{(1S,2S,4R)-7,7-dimethyl-1-[(pyrrolidin-1-yl)methyl]bicyclo[2.2.1]heptan-2-yl}-1H-benzo[d]imidazole, prepared from camphor derived diamine, is disclosed. The absolute configuration at the chiral center bearing benzo[d]imidazole moiety was confirmed by NOESY. structure a newly synthesized compound 1H- and 13C-NMR, 2D NMR, IR spectroscopy, high resolution mass-spectrom...

A wide range of 4,6-diarylated/heterylated pyridin-2(1H)-one derivatives were synthesized in good to excellent yields from 1,3-diarylated/heterylated-2-propen-1-ones (chalcones) in one pot under metal and base-free conditions. This domino reaction suggests a novel mechanism comprising of Michael addition followed by amination, subsequent intramolecular amidation and finally dehydronitrosation. ...

The 5-amino-(cyanoformimidoyl)-1H-imidazole has been prepared from amidine by treatment with barium hydroxide in ethanol. 2-(4-Isopropylbenzyl)-6-carbamoyl-1, 2-dihydropurine was obtained from 5-amino-4-(cyanoformimidoyl)-1H-imidazole and isopropylbenzaldehyde in dry methanol. All compounds have been fully characterized by spectroscopic data.

Objective: Cancer is one of the major causes of death worldwide irrespective of the sex. The aim of the study was to design, synthesize, and identification of novel anti-proliferative agents that can potently target cancer. Methods: We are reporting the synthesis of the new series of N-substituted 2-(2-butyl-4-chloro-1H-imidazole-5-yl)-1H-benzo[d]imidazole derivatives and evaluated for their an...

A microwave-assisted protocol was developed for the construction of 2-amino-1H-imidazole/triazole conjugates starting from the previously described 2-hydroxy-2,3-dihydro-1H-imidazo[1,2-a]pyrimidin-4-ium salts. The process involves a one-pot hydrazinolysis/Dimroth-rearrangement of these salts followed by a ligand-free copper nanoparticle-catalyzed azide-alkyne Huisgen cycloaddition. The 2-amino-...

a new type of magnetically-recoverable catalyst was synthesized by the immobilization of h3pw12o40 on the surface of silica-encapsulated -fe2o3 nanoparticles. a series of novel 1,3,5-triaryl pyrazoline derivatives has been synthesized by the reaction of chalcone and phenylhydrazine in the presence of the -fe2o3@sio2-pw12nanoparticles,  in high yields. the structures of compounds obtained were...
