A new series of N-[5-(4-(alkyl/aryl)-3-nitro-phenyl)-[1,3,4-thiadiazol-2-yl]-2,2-dimethyl-propionamide 4 (a-l) and 6-(4-Methoxy-phenyl)-2-(4-alkyl/aryl)-3-nitro-phenyl)-Imidazo [2,1-b] [1,3,4] thiadiazole 6 (a-l) were synthesized starting from 5-(4-Fluoro-3-nitro-phenyl)-[1,3,4] thiadiazole-2-ylamine. The synthesized compounds were characterized by IR, NMR, mass spectral and elemental analysis....

Hi, neighbor! The first organocatalyzed asymmetric transfer hydrogenation of aromatic nitro compounds was successfully developed with up to 99 % ee. The new methodology provides a direct and facile access to enantiopure cyclic nitro compounds with two contiguous stereocenters.

Palladium nanoparticles (NPs) stabilized by ImS3-14, a zwitterionic surfactant structurally related to ionic liquids, are revealed here to be good catalysts for the reduction of a large number of substituted aromatic nitro compounds. Our mass spectrometry results are consistent with the formation of amino products in a direct route, where the aromatic nitro compounds are initially reduced to ni...

Several cycline dependent kinase 2 (CDK2) inhibitors with different chemical structures have been introduced. The hinge region of CDK2 (residues 81–84) contains a set of hydrogen bond donor and acceptor sites some of which must be satisfied for potent inhibitor binding. The benzimidazolone skeleton may provide such interactions. Accordingly, 3-sulfonamide substituted benzamido-benzimidazolones ...

Nitro compounds are an important class of organic molecules with broad application in synthesis, medicinal chemistry, and materials science. Among the variety methodologies available for their direct oxidation primary amines represents attractive alternative route. Efforts towards development oxidative procedures synthesis nitro derivatives have spanned over past decades, leading to a wide prot...

A new electron capture detector (ECD) for the Agilent 6890 Series gas chromatograph (GC) allows very sensitive detection of nitroaromatic compounds at low picogram levels with a linear response over three orders of magnitude. Analysis of Nitroaromatics and Nitro-Polycyclic Aromatic Hydrocarbons by Capillary Gas Chromatography with the Agilent 6890 Micro-ECD This application note describes the p...
