Заглавие : 15N chemical shifts and Jnn-couplings as diagnostic tools for determination of the azide-tetrazole equilibrium in tetrazoloazines
Место публикации : Journal of Organic Chemistry. - 2022. - Vol. 87, № 1. - С. 211–222
Предметные рубрики: ХИМИЧЕСКИЕ НАУКИ
Аннотация: Selectively 15N-labeled tetrazolo[1,5-b][1,2,4]triazines and tetrazolo[1,5-a]pyrimidines bearing one, two, or three 15N labels were synthesized. The synthesized compounds were studied by 1H, 13C, and 15N NMR spectroscopy in DMSO and TFA solutions, where the azide–tetrazole equilibrium can lead to the formation of two tetrazole (T, T′) isomers and one azide (A) isomer for each compound. Incorporation of the 15N-label(s) leads to the appearance of 15N–15N coupling constants (JNN), which can be easily measured via simple 1D 15N NMR spectra, even at natural abundance between labeled and unlabeled 15N atoms. The chemical shifts for the 15N nuclei in the azole moiety are very sensitive to the ring opening and azide formation, thus providing information about the azido–tetrazole equilibrium. At the same time, the 1–2JNN couplings between 15N-labeled atoms in the azole and azine fragments unambiguously determine the fusion type between tetrazole and azine rings in the cyclic isomers T and T′. Thus, combined analysis of 15N chemical shifts and JNN values in selectively isotope-enriched compounds provides an effective diagnostic tool for direct structural determination of tetrazole isomers and azide form in solution. This method was found to be the most simple and efficient way to study the azido–tetrazole equilibrium.

Аннотация: The nitration of 5,7-dimethyl-2-polyhaloalkylchromones affords either 5,7-dimethyl-6-nitro- or 5,7-dimethyl-6,8-dinitro-2-polyhaloalkylchromones, depending on the reaction conditions. Signals in the 1H and 13C NMR spectra of the sterically hindered chromones were completely assigned using the 2D NOESY, HETCOR, and COLOC spectra. The influence of nonplanar nitro groups on chemical shifts of carbon atoms was studied. Some spectral peculiarities of the peri-methyl group were revealed. The 1H-1H and 13C-1H spin-spin coupling constants, including the extreme six-bond long-range coupling between the protons of the Me(5) group and H(8), were determined

Ключевые слова (''Своб.индексиров.''): 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.??????--------------------------------------------------------------------------------??

Аннотация: Acidic hydrolysis of N-acyl 1-methyl- and 1-phenyl-3-amino-1,2-dicarba-closo-dodecaboranes has been studied. It has been shown that acidic hydrolysis of diastereomeric amides of 1-methyl-3-amino-1,2-dicarba-closo-dodecaborane results in the partial racemization of the target 3-amino-1-methylcarborane. Under the similar conditions, the hydrolysis of N-acyl-3-amino-1-phenyl-1,2-dicarba-closo-dodecaboranes resulted in amide bond cleavage accompanied by simultaneous deboronation with the removal of boron atom at position 6 of carborane cage and formation of 7,8-dicarba-nido-undecaborane derivative according to 11B and 1H NMR spectroscopy.

Аннотация: Reaction of N-alkylated imidazoles with 2-chloro-4-quinazolinone gave mesomeric betaines, 2-(1-alkyl-1H-imidazolium-3-yl)quinazolin-4-olates, for which three tautomeric forms of N-heterocyclic carbenes (NHCs) can be formulated, in addition to an anionic NHC after deprotonation. The NHC tautomers were trapped with sulfur, selenium, triethylborane, and triphenylborane as thiones, selenones and borane adducts, respectively. We obtained two isomers of the cyclic borane adducts, diazaboroloquinazolinones with [1,5-a] and [5,1-b]-type fusion between the quinazolinone and the diazaborole rings. They correspond to two different NHC tautomers and to the anionic NHC derived thereof. The third NHC tautomer was trapped as a non-cyclic adduct with tris(pentafluorophenyl)borane by coordination to the quinazoline oxygen atom. 2D 1H-15N HMBC experiments of 15N-labeled quinazolinone fragments, quantitative measurements of long-range 1H-15N coupling constants (JHN), and five X-ray single crystal analyses have been carried out for the structure elucidations and to gain insight into the NMR spectroscopic properties of these compounds.

Ключевые слова (''Своб.индексиров.''): chitosan--chemical modification--gel technique
Аннотация: This study presents a new approach for direct carboxyalkylation of chitosan in the gel state by using aza-Michael addition and substitution reactions. Various reagents were applied including acrylic and crotonic acids, and alpha-, beta-, gamma-, delta-, and epsilon-halocarboxylic acids. The reaction of chitosan with gamma- and delta-halocarboxylic acids showed no target product formation either in solution or in the gel state. In the case of acrylic, crotonic, alpha- and beta-halocarboxylic acids, the reaction performed in the gel state (concentration of chitosan 20-40%) shows higher degree of substitution at lower reaction time and temperature than in diluted solutions (concentration of chitosan 0.5-2%). The results were discussed in terms of kinetics of the target and side reactions. H-1 and C-13 NMR confirmed that in all cases the carboxyalkylation of chitosan proceeds exclusively at the amino groups

Ключевые слова (''Своб.индексиров.''): chitosan--acetaldehyde acetals--hydrogel
Аннотация: Here we demonstrate the possibility of using acyclic diethylacetal of acetaldehyde (ADA) with low cytotoxicity for the fabrication of hydrogels via Schiff bases formation between chitosan and acetaldehyde generated in situ from acetals in chitosan acetate solution. This approach is more convenient than a direct reaction between chitosan and acetaldehyde due to the better commercial availability and higher boiling point of the acetals. Rheological data confirmed the formation of intermolecular bonds in chitosan solution after the addition of acetaldehyde diethyl acetal at an equimolar NH2: acetal ratio. The chemical structure of the reaction products was determined using elemental analysis and 13C NMR and FT-IR spectroscopy. The formed chitosan-acetylimine underwent further irreversible redox transformations yielding a mechanically stable hydrogel insoluble in a broad pH range. The reported reaction is an example of when an inappropriate selection of acid type for chitosan dissolution prevents hydrogel formation.

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

Аннотация: Describing the crystal structure, packing, FT-IR, UV-Vis and NMR spectra and thermal properties of new polydentate O-ligand based on aryl-beta-diketone moieties connected by ethylene glycol spacer is the subject of this article. The results of IR, UV-Vis and H-1 NMR spectroscopy as well X-ray crystallography of 1,2-bis[2-(4,4,4-trifluoro-1-hydroxy-3-oxobut-1-enyl)phenoxy]-ethane (BTFPE) indicate that the compound exists in solution and in solid as enol. The crystal structure analysis shows that BTFPE has C2/c group of the monoclinic system. Typical S(6) intramolecular hydrogen bond occurs in each 1,3-diketo moiety. This bond is asymmetric and the H atom is closest to the 0 atom adjacent to the phenyl ring. The packing of the crystal is sustained by numerous C-H center dot center dot center dot O, O-H center dot center dot center dot F, C-H center dot center dot center dot F interactions. In the crystal, supramolecular zig-zag chains are formed along the c-axis. Short contacts interconnect the molecules into a two-dimensional layered structure wherein each molecule is node between chains. According to the thermal investigation this compound is stable up to 200 degrees C in air atmosphere, above this temperature it decomposes. Photoluminescent properties of aluminum(III) and europium(III) complexes of BTFPE were evaluated in chloroform solution and in the solid state. Aluminum complex of BTFPE shows blue luminescence with maximum at 445 nm.
