SYNTHESIS -- PYRAZINONES -- CRYSTAL STRUCTURES
Аннотация: A simple method for the synthesis of 5-(het)aryl-3-cyano-1-ethyl-2(1H)-pyrazinones was proposed. The method is based on the hydrolysis of the corresponding 2,3-dicyanopyrazinium salts. The spectral properties of pyrazinones were studied and their crystallographic investigation was carried out. The possibility of introduction of 5-(het)aryl-3-cyano-1-ethyl-2(1H)-pyrazinones into the [2+4] cycloaddition under the microwave activation conditions was sho

AMIDES -- DIASTEREOISOMERS -- ENANTIOMERS
Аннотация: Enantiomers of 2-methyl-6-nitro-1,2,3,4-tetrahydroquinoline have been obtained by kinetic resolution of racemic 2-methyl-1,2,3,4-tetrahydroquinoline in acylation with acyl chlorides of N-protected amino acids followed by regioselective nitration of the diastereoisomeric amides and acidic hydrolysis. The introduction of a trifluoroacetyl protecting group into the position 1 of the enantio pure nitro compound followed by the reduction led to (S)-6-amino-2-methyl-1-trifluoroacetyl-1,2,3,4-tetra-hydroquinoline in a high yield

PYRAZINES -- ANTITUBERCULOSIS ACTIVITY -- 2(1H)-PYRAZINONE
Аннотация: A simple method based on hydrolysis of 2,3-dicyanopyrazinium salts has been used for the synthesis of the corresponding 5-(hetero)aryl-3-cyano-1-ethyl-2(1H)-pyrazinones. Also, the series of novel 1-ethyl-5-(hetero)aryl-1,6-dihydropyrazine-2,3-dicarbonitriles have been obtained through reduction of the same pyrazinium salts with triethylsilane. The obtained compounds proved to be active in micromolar concentrations in vitro against Mycobacterium tuberculosis H37Rv, Mycobacterium avium, Mycobacterium terrae, as well as against rifampicin and isoniazid-resistance strains of Mycobacterium tuberculosis. The data for acute in vivo toxicity in mice have been obtained for these compounds which appear to be promising antitubercular agents

Аннотация: The sol-gel synthesis of titanium dioxide from titanium glycerolate (TG) and titanyl sulfate was studied. The effect of hydrothermal treatment in an autoclave at 130 C and refluxing TG with the peroxo titanium acid gel on the product properties, i.e.; morphology of the nanoparticles and their aggregates, as well as their ability to adsorption and photocatalytic degradation of methylene blue in aqueous solutions was discussed

"SOL-GEL" MATERIALS -- AMINOPOLYSILOXANES -- SPECIFIC SURFACE AREA
Аннотация: The hybrid materials based on polysiloxane modified by amino groups have been synthesized by the sol-gel method. Aminated polysiloxane has been prepared by the copolycondensation reaction of tetraethoxysilane with gamma-aminopropyltriethoxysilane (APS-1) and through the modification of the product (APS-2) of the hydrolysis of tetraethoxysilane by gamma-aminopropyltriethoxysilane. The composition of sorbents has been confirmed by the elemental analysis and IR Fourier spectroscopy. The high degree of sorption extraction of copper(II), nickel(II), cobalt(II), zinc(II), cadmium(II), and lead(II) ions in the case of their coexistence in an ammonia-acetate buffer solution has been observed for polysiloxanes APS-2. The synthesized surface-modified materials exhibit the highest selectivity to nickel(II) and cobalt(II) ions

Аннотация: 1H and 29Si NMR spectroscopy showed that the product of the reaction of dimethyldiethoxysilane with glycerol in the molar ratio 1: 2 is an equilibrium mixture of dimethyldiglyceroxysilane and low-molecular-weight condensation products. The change of viscosity of silicon dimethylglycerolates, synthesized using different excesses of glycerol, versus time was studied by viscosimetry. Composition of products of hydrolysis and condensation of silicon dimethylglycerolates is determined by their concentration in the starting aqueous solutions
