Кл.слова (ненормированные):
A green protocol has been developed for the synthesis of simple coumarins and linear pyrano[2,3-f] and [3,2-f]indoles by the reaction of phenol derivatives with β-ketoesters under ball milling at ambient temperature in the presence of methanesulfonic acid as a mild acid catalyst. The significant advantages of this procedure are high yields, scalability, no use of hazardous acids or solvents, shorter reaction time, ambient temperature, low cost, and straightforward purification without column chromatography. This procedure is associated with high EcoScale metrics and a low E-factor. In contrast to traditional Pechmann condensation procedures, the mechanochemical protocol leads to the synthesis of pyranoindoles with excellent regioselectivity and high yields.

Аннотация: The reactions of alkyl tri-and tetrafluorosalicylates with diethylamine led to formation of the stable salts regardless of the conditions. Therein, ethyl esters were undergone dealkylation leading to formation of diethylammonium carboxylates. Methyl tetrafluorosalicylate was subject to similar transformations, while trifluoro-containing analog gave salt at the hydroxyl group and in which ester fragment was remained.

LIGANDS
Аннотация: The reactions of copper(II) and cobalt(II) mixed complexes based on methyl trifluorosalicylate and 2,2’-bipyridine and 1,10-phenanthroline with 1,1,1,3,3,3-hexafluoropropan-2-ol (HFIP) as the Lewis acid were investigated. In the case of copper(II) complexes, the hydrolysis of ester fragment occurred to form heteroligand complexes of trifluorosalicylic acid and bipyridine-like ligand associated with fluorinated alcohol. The structure of complexes corresponded to [Cu(L3-H2)(bipy or phen)*(HFIP), L3 −trifluorosalicylic acid]. In contrast, cobalt(II) complexes in refluxing HFIP resulted in the complexes [Co(L1-H)2(bipy or phen)*(HFIP), L1 – methyl trifluorosalicylate], in which the ester ligand was preserved.

DIPEPTIDES -- RACEMIZATION -- PURINE -- COUPLING -- NUCLEOPHILIC SUBSTITUTION -- ANTIMYCOBACTERIAL ACTIVITY
Аннотация: The synthesis of purine conjugates with natural amino acids is one of the promising directions in search for novel therapeutic agents, including antimycobacterial agents. The purpose of this study was to synthesize N-(purin-6-yl)dipeptides containing the terminal fragment of (S)-glutamic acid. To obtain the target compounds, two synthetic routes were tested. The first of them is based on coupling of N-(purin-6-yl)-(S)-amino acids to dimethyl (S)-glutamate in the presence of carbodiimide coupling agent followed by the removal of ester groups. However, it turned out that this coupling process was accompanied by racemization of the chiral center of N-(purin-6-yl)-α-amino acids and in all cases led to mixtures of (S,S)- and (R,S)diastereomers (6:4). Individual (S,S)-diastereomers were obtained using an alternative approach based on the nucleophilic substitution of chlorine in 6-chloropurine or 2-amino-6-chloropurine with corresponding dipeptides as nucleophiles. The enantiomeric purity of the target compounds was confirmed by chiral HPLC. To test the assumption that racemization of the chiral center of N-(purin-6-yl)-α-amino acids occurs with the participation of nitrogen atoms of the imidazole ring via the stage of formation of a chirally labile intermediate, we obtained such structural analogs of N-(purin-6-yl)-(S)-alanine as N-(9-benzylpurin-6-yl)-(S)-alanine and N-(7-deazapurin-6-yl)-(S)-alanine. It was found that coupling of these compounds to dimethyl (S)-glutamate was also accompanied by racemization. This indicates that the imidazole fragment does not play a crucial role in this process. When testing the antimycobacterial activity of some of the obtained compounds, conjugates with moderate activity against the laboratory Mycobacterium tuberculosis H37Rv strain (MIC 3.1–6.25 μg/mL) were identified.

6-CHLOROPURINE -- HETEROCYCLIC AMINES -- ANTIVIRAL ACTIVITY -- INFLUENZA A AND B VIRUSES
Аннотация: A number of novel amides were synthesized by coupling of 6-[(9H-purin-6-yl)amino]hexanoic acid to heterocyclic amines. The antiviral activity of the obtained compounds, as well as of purine conjugates in which 7,8-difluoro-3-methyl-3,4-dihydro-2H-1,4-benzoxazine is linked to position 6 of purine through a fragment of ɷ-amino acids with varying lengths of polymethylene chains against influenza A and B viruses was studied in vitro. Purine derivatives have been shown to have moderate activity against influenza A (H1N1) virus. The antiinfluenza activity and cytotoxicity of conjugates with 7,8-difluoro-3-methyl-3,4-dihydro-2H-1,4-benzoxazine depend on the length of the linker fragment.

HYDROGELS -- CHITOSAN -- SALICYLALDEHYDE
Аннотация: Here, we discuss the applicability of (methylenebis(salicylaldehyde)—MbSA) for the fabrication of the stimuli-responsive N-carboxyethylchitosan (CEC) hydrogels with a tunable dissolution rate under physiological conditions. In comparison with non-covalent salicylimine hydrogels, MbSA cross-linking via covalent bis(‘imine clip’) and non-covalent hydrophobic interactions allowed the fabrication of hydrogels with storage moduli > 1 kPa at ten-fold lower aldehyde/CEC molar ratio with the preservation of pH- and amino-acid responsive behavior. Although MbSA-cross-linked CEC hydrogels were stable at neutral and weakly alkaline pH, their disassembly in cell growth medium (Dulbecco’s modified Eagle’s medium, DMEM) under physiological conditions was feasible due to transimination reaction with amino acids contained in DMEM. Depending on the cross-linking density, the complete dissolution time of the fabricated hydrogels varied from 28 h to 11 days. The cytotoxicity of MbSA cross-linked CEC hydrogels toward a human colon carcinoma cell line (HCT 116) and primary human dermal fibroblasts (HDF) was remarkably lower in comparison with CEC-salicylimine hydrogels. Fast gelation, relatively low cytotoxicity, and tunable stimuli-induced disassembly under physiological conditions make MbSA cross-linked CEC hydrogels promising for drug encapsulation and release, 3D printing, cell culturing, and other biomedical applications.

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.

Аннотация: Di(het)areno[e,l][1,3]diazapyrene core was constructed by FeCl3-mediated intramolecular oxidative cyclodehydrogenation of 5-[2,6-di(het)arylphenyl]pyrimidine precursors, which in turn were obtained by the Suzuki cross-coupling of 5-(2,6-dibromophenyl)pyrimidine derivative with the corresponding (het)arylboronic acids. Molecular orbital calculations as well as redox and photophysical measurements show that the fused products are promising for organic electronic application.
