KINETIC RESOLUTION -- ACYL CHLORIDES -- ENANTIOMERS
Аннотация: Kinetic resolution of racemic 3 methyl 2,3 dihydro 4H [1,4]benzoxazines in the reaction with chiral 2 arylpropionyl chloride predominantly yielded R*,R* diastereomers. Ibuprofen acyl chloride as acylating agent was found to be more selective and sensitive to the changes in the reaction temperature as compared to naproxen acyl chloride and 2 phenylpropionyl chloride

RACEMIC FLUORINATED -- 1,2,3,4-TETRAHYDROQUINOLINES -- BENZOXAZINES
Аннотация: The acylative kinetic resolution of racemic 6-fluoro-2-methyl-1,2,3,4-tetrahydroquinoline, 7,8-difluoro-3,4-dihydro-3-methyl-2H-[1,4]benzoxazine, and their non-fluorinated analogues with (S)-naproxen and N-phthaloyl-(S)-amino acyl chlorides has been carried out. It has been shown that the presence of fluorine atoms in the aromatic fragment of a heterocyclic amine results in the increasing stereoselectivity of acylation with (S)-naproxen acyl chloride and in a decrease in the efficiency of acylative kinetic resolution using N-phthaloyl-(S)-amino acyl chlorides. A method for the preparation of enantiopure (S)-6-fluoro-2-methyl-1,2,3,4-tetrahydroquinoline (ee >99%) was developed

TRIAZINE SYNTHESIS -- 1,3-DICARBONYL -- ISOMERISM
Аннотация: Azo coupling of 1,3-dicarbonyl compounds with tetrazolyl-5-diazonium chloride is used to develop a convenient one-step procedure for the synthesis of 4,7-dihydrotetrazolo[5,1-c][1,2,4]triazines. In contrast to nonfluorinated analogs, 7-hydroxy-7-polyfluoroalkyl-4,7-dihydrotetrazolo[5,1-c][1,2,4]triazines undergo a ring-chain isomerism resulting from the cleavage at the C7 - N7a bond. A distinctive feature of nonfluorinated 4,7-dihydrotetrazolo[5,1-c][1,2,4] triazines is the possibility to dehydration, which is accompanied by an azide rearrangement due to the tetrazole ring cleavage with the formation of tetrazolo[1,5-b][1,2,4]triazines

Аннотация: A series of new polycyclic compounds bearing the 5,11-dihydroindolo[3,2-b] carbazole ring system, as the common motif of their nine-ring scaffolds, has been successfully prepared with the usage of an efficient two-step strategy, based on the double Friedel-Crafts acylation of 5,11-dihexyl-6,12-di(hetero) aryl-substituted 5,11-dihydroindolo[3,2-b] carbazoles with 2-iodobenzoyl chloride in the presence of SnCl4, followed by regioselective palladium-catalyzed cyclization of the obtained 2,8-bis(2-iodobenzoyl) derivatives into the desired fused 9H-fluoren-9-ones. Some modifications of these nine-ring structures have been performed to afford compounds of the same family bearing the 9H-fluorene fragments. Basic photophysical and electrochemical properties as well as thermal stability of the new fused indolo[3,2-b] carbazole derivatives have been determined.

Аннотация: A comparative study of the kinetic resolution of racemic 2-methyl-1,2,3,4-tetrahydroquinoline and 2,3-dihydro-3-methyl-4H-1,4-benzoxazine using N-phthaloyl-(S)-amino acyl chlorides as chiral acylating agents is described. Temperature and solvent effects on the stereochemical features have been examined. It has been found that N-phthaloyl-(S)-phenylalanyl and N-phthaloyl-(S)-2-phenylglycyl chlorides bearing aromatic substituents close to the stereogenic centre are more stereoselective acylating agents than N-phthaloyl-(S)-alanyl chloride. For the preparative kinetic resolution of racemic amines N-phthaloyl-(S)-phenylalanyl chloride proved to be the most appropriate chiral acylating agent

It has been found that acylation of 3,4-dihydro-3-methyl-2H-[1,4]benzothiazine proceeds with the best stereoselectively when compared with other racemic amines. An efficient method for the preparation of (S)-3,4-dihydro-3-methyl-2H-[1,4]benzothiazine (99.4% ee) via a kinetic resolution protocol was developed. The possibility of recycling (R)-2-phenoxypropionic acid has been demonstrated.

Аннотация: Meanwhile 5-aryl-6-cyano-2,2-bipyridines are very stable towards various nucleophiles, addition copper(II) chloride to the reactional mixture facilitates nucleophilic addition to the cyano group dramatically. The cyanobipyridines react easily with water, methanol, ethanolamine in the presence of CuCl2 yielding well-crystallized complexes containing carboxylates, carboximidates or carboxamidines as ligands. 5-Cyano-1,2,4-triazines are more active in the reactions due to higher electron-withdrawing properties of this heterocycle. Due to the same reason acetylene moiety of 5-ethynyl-3-pyridyl-1,2,4-triazine adds water quite easily but in the presence of copper chloride as well

POLYSTYRENE -- CHLOROMETHYLATION -- SYNTHESIS IN GEL
Аннотация: A new method for the preparation of poly(chloromethylstyrene) by synthesis in a gel via treating of linear polystyrene with cyclic formals in thionyl chloride has been developed. The method allows to obtain a polymer with a high degree of functionalization. The degree of chloromethylation depends on the molar ratio of the reagents and the catalyst used. The reactivity of the formals increases in the series 1,3-dioxolane < trioxane < paraform. The composition and structure of polymer products were characterized by elemental analysis, FTIR spectroscopy, and thermogravimetry. It is established that carrying out of chloromethylation in gel allows, in comparison with the known methods, to achieve a greater degree of functionalization faster and with lower consumption of reagents and solvents.

The reaction of LiL with praseodymium(III) nitrate gives the new trimetallic structure [(LiPrL3)(LiL)(NO3)(H2O)2] (CIF file CCDC no. 2031103 (II)), and the replacement of nitrate by chloride gives [(PrL3)(LiL)(H2O)] (CIF file CCDC no. 2031104 (IIIa)). Regardless of the nature of the anion of the salt in the series from neodymium(III) to ytterbium(III) and yttrium(III), Ln–Li β-diketonates [(LnL3)(LiL)(solv)] (solv is H2O and MeOH) are formed, and their structures are characterized by X-ray structure analysis (CIF files CCDC nos. 2031099 (IIIb), 2031100 (IIIc), 2031098 (IVa), 2031096 (IVc), 2031094 (IVf), 2031101 (IVg), and 2031095 (IVh)). The equilibrium of the diketonate isomeric forms in a solution of deuterated dimethyl sulfoxide is studied by 19F NMR spectroscopy, and the qualitative composition of the polynuclear complexes is determined by mass spectrometry.

CHITOSAN -- SORBENT -- GOLD(III)
Аннотация: A novel method for the synthesis of a hetaryl containing chelate amino polymer, namely, N (4(5) imidazolylmethyl)chitosan (IMC), with a degree of substitution up to 0.3 was pro posed. The "synthesis in gel" approach involves direct substitution of the hydroxyl group in 4(5) imidazolylmethanol. The structures of these polymers were confirmed by 1H NMR data. For sorption studies, IMC samples were crosslinked with epichlorohydrin and diglycidyl ethers of ethylene glycol and diethylene glycol. The degrees of swelling and sorption properties of the polymers largely depend on the crosslinking agent and the degree of crosslinking. The sorption capacities of IMC for AuIII, PtIV, and PdII ions are higher than those of the nonmodified polymer. The extraction of noble metal ions from chloride solutions becomes more selective with increasing degree of crosslinking. The sorption capacity of IMC for CoII and NiII ions is higher than those of chitosan and its known N heterocyclic derivatives

Аннотация: A comparative study of the kinetic resolution (KR) of racemic 6-substituted 2-methyl-1,2,3,4-tetrahydroquinolines with acyl chlorides of (S)-naproxen, N-phthaloyl-(S)-leucine, and (R)-O-phenyllactic acid was carried out. The selectivity factors in the KR of racemic amines with acyl chlorides of (S)-naproxen and (R)-O-phenyllactic acid were shown to be approximately the same and higher than those for the KR of N-phthaloyl-(S)-leucyl chloride. The reasons for the stereodifferentiation in the KR of racemic tetrahydroquinaldines containing groups of different electronic properties by acyl chlorides of three different chiral acids were explained using the DFT method. The conditions for stabilizing π—π interactions of aromatic fragments of the reagents, which do not occur in the same form in the transition state and lead to the minor diastereoisomeric product, are created in the transition state of the faster acylation reaction with (S)-naproxen and (R)-O-phenyllactic acyl chlorides. In the case of the KR of 2-methyl-1,2,3,4-tetrahydroquinoline and 2-methyl-6-methoxy-1,2,3,4-tetrahydroquinoline with N-phthaloyl-(S)-leucyl chloride, the acylation diastereoselectivity is determined, most likely, by conformational factors. The individual (S)-enantiomer of 2-methyl-6-methoxy-1,2,3,4-tetrahydroquinoline of high optical purity was synthesized using the KR of the racemate with (S)-naproxen acyl chloride.
