Аннотация: A new type of ring-chain tautomerism, which consists of the reversible conversion of bicyclo[4.2.0]octane derivatives into trisubstituted enamines was found and studied by 1H NMR spectroscopy. The starting materials were prepared by the stereoselective reaction of (E)-3,3,3-trichloro-1-nitropropene with cyclohexanone enamines

Аннотация: The solubility of chitosan in aqueous solutions of lithium and magnesium halides varies in the order: LiCl LiBr LiI; MgCl2 MgBr2 MgI2. A method for selective production of mono-N-(2-carboxyethyl)chitosan (NCE-chitosan) was developed by synthesis in gel (concentration of chitosan 4-20%) of the magnesium halides solution (1.1-3.5 M) using acrylic acid. Using for reaction of MgI2 or MgBr2 provides relative greater amount of the monosubstituted amino groups (73-87%) in comparison with their absence (50-70%) at the high degree of substitution (DS) more than 0.7. DS of the prepared NCE-chitosan and the ratios mono-: disubstitution of amino groups was determined by 1H NMR spectroscopy. The chemical structure of the obtained NCE-chitosan was characterized by FT-IR and 13C NMR spectroscopies

In a dichloromethane solution, these cyclic nitronates undergo diastereoselective ring opening to produce nitroalkylated anti-CCl3- and syn-CF3-enamines, which are hydrolysed with dilute HCl to afford the respective anti-CCl3- and syn-CF3-g-nitroketones

Аннотация: N-(3-Hydroxypropyl)-beta-alanine was synthesized by the reacti on of 3-aminopropanol with acrylic acid. From this ligand and basic copper carbonate, bis(N-(3-hydroxypropyl)-beta-alaninato)dicopper(II) [Cu2 (C6H11NO3)2] was obtained. The structures of the chelating agent and the copper complex were studied by X-ray diffraction. The Cu(II) coordination polyhedron is a distorted square pyramid. Each ligand forms six-membered ?-alaninate and propanolamine chelate rings. The propoxy group functions as a bridge. In the crystal structure, the molecules form intermolecular coordination bonds C=OCu, which are perpendicular to the layers. The EPR signal typical of dimeric copper complexes is not observed due to low occupancy of the excited paramagnetic triplet state. The weak paramagnetic signal from monomeric copper complex allowed recording of the 1H NMR spectrum of [Cu2 (Pro-ala) 2] with characteristic line broadening and contact shift. It follows from the obtained data that on dissolution, the complex dissociates by 40% to give monomeric copper complexes

3-CYANOCHROMONES -- PRIMARY AMINES -- RECYCLIZATION
Аннотация: Reactions of 3-cyanochromones with primary aromatic amines in boiling benzene gave mixtures of Z- and E-3-arylamino-2-(2-hydroxyaroyl)acrylonitriles and 2-amino-3-(aryl-iminomethyl)chromones. The latter can easily be obtained in the individual state when the reaction is carried out in the presence of triethylamine. In the case of primary aliphatic amines, the open-chain reaction product immediately undergoes cyclization into 3-alkyliminomethyl-2-aminochromones. The structures of the products were examined by 1D and 2D 1H, 13C, and 15N NMR spectroscopy in DMSO-d6 and CDCl3

Аннотация: The acylative kinetic resolution of racemic 2-methyl-1,2,3,4-tetrahydroquinoline and 2,3-dihydro-3-methyl-4H-1,4-benzoxazine using acyl chlorides of N-phthaloyl-(S)-phenylalanine, N-phthaloyl-3-(4-nitrophenyl)-(S)-alanine and N-phthaloyl-O-methyl-(S)-tyrosine as chiral resolving agents has been carried out. It is shown that the effectiveness of an acylative kinetic resolution depends on the electronic effects of substituents in the phenyl fragment of the acylating agent and increases as the electron-donating properties of the para-substituent (OMe H NO2) in phenyl fragment of N-phthaloyl-3-aryl-(S)-alanyl chlorides increase; conducting the process at a reduced temperature also contributes to an enhancement of the kinetic resolution

LAMELLARIN ALKALOIDS -- ISOQUINOLINE DERIVATIVES -- HETEROCYCLIC SYSTEM
Аннотация: The basic structural framework of lamellarin alkaloids, 8,9-dihydro-6H-chromeno[4?,3?:4,5]pyrrolo[2,1-a]isoquinoline derivatives, has been obtained in good yields via Grob synthesis between 3-nitro-2-(trifluoromethyl)-2H-chromenes and 1-methyl-3,4-dihydroisoquinolines in refluxing isobutanol. In the case of 1-benzyl-3,4-dihydroisoquinolines, a dynamic NMR effect was observed in the 1H and 19F NMR spectra of the products as a result of restricted rotation about the single bond linking the benzene ring and the heterocyclic system. When the reaction was carried out with 3-nitro-2-(trichloromethyl)-2H-chromenes in toluene at room temperature, only Michael adducts, as a mixture of two diastereomers, were isolated.??????--------------------------------------------------------------------------------??

CHITOSAN N-HETEROCYCLIC DERIVATIVES -- SELECTIVE ADSORPTION -- PYRIDINE DERIVATIVES
Аннотация: The method of producing N-2-(2-pyridyl)ethylchitosan (PE-chitosan) with substitution degrees (DS) up to 1.2 has been developed using the "synthesis in gel" approach for direct addition reaction between 2-vynilpyridine and chitosan. Investigation of sorption properties has revealed significantly higher affinity of pyridylethyl fragments to Pt(IV)) and Pd(II) ions compared to the unsubstituted amino groups of chitosan. The maximum sorption capacities of PE-chitosan in 0.1 M HCl solution were estimated as 5.56 mmol/g for Au(III), 3.67 mmol/g for Pd(II), and 2.75 mmol/g for Pt(IV). Sorption capacities of PE-chitosan for transition metal ions at pH 4-8 were 1.5-2.6 higher than those of chitosan with the highest values attained for Cu(II) and Ag(I) ions - 1.50 mmol/g and 1.53 mmol/g, respectively. The PE-chitosan application for preconcentration of Au(III) with subsequent elution with HCl/thiourea mixtures was proved to be efficient for atomic absorption spectroscopy analysis of multi-component solutions with low gold content
