Аннотация
For a comprehensive assessment of the enantiomeric stereospecificity of human soluble epoxide hydrolase (hsEH), 1,3-disubstituted ureas and thioureas containing a bornyl fragment in their structure were synthesized according to the reaction exo-(R or S)-1,1,7-trimethylbicyclo[2.2.1]heptane-2-amine with aromatic isocyanates and isothiocyanates with yields up to 99%. Synthesized compounds are promising inhibitors of hsEH.

Formation of 1-(2,4,6-trifluorophenyl)perfluorobenzocyclobutene from perfluorobenzocyclobutene and 1,3,5-trifluorobenzene and its interaction with polyfluorobenzenes in an SBF5 medium
Аннотация
Interaction of perfluorobenzocyclobutene with two equivalents of 1,3,5-trifluorobenzene in an SbF5 medium followed by the treatment of the reaction mixture with water gave (3,4,5,6-tetrafluorobenzene-1,2-diyl)bis[(2,4,6-trifluorophenyl)methanone], 1-(2,4,6-trifluorophenyl)perfluorobenzocyclobuten-1-ol and 4,5,6,7-tetrafluoro-1,3,3-tris(2,4,6-trifluorophenyl)-1,3-dihydro-2-benzofuran-1-ol. When the reaction mixture was treated with HF, 1,2-bis(2,4,6-trifluorophenyl)-perfluorobenzocyclobutene along with 1-(2,4,6-trifluorophenyl)perfluorobenzocyclobutene were obtained. The latter compound reacted with pentafluoro-, 1,2,3,4- or 1,2,4,5-tetrafluorobenzenes in an SbF5 medium to give corresponding polyfluoro-1,2-diphenylbenzocyclobutenes after treatment of the reaction mixture with HF.

Аннотация
Double alkylation reactions of aromatic hydrocarbons with carboxylic acids and hydroxy-substituted mono- and dicarboxylic acids in acidic media have been carried out. The obtained polycarboxylic diadamantylated arenes can be considered as a new type of structurally rigid polycarboxylate ligands in the directed design of metal-organic coordination frameworks.

Аннотация
The diverse biological activity of heterocyclic compounds makes them one of the most important areas of pharmaceuticals and organic synthesis. In this work, a synthesis of new hetarylquinolines containing thiazolidine and dihydrothiazole rings was carried out on the basis of 2-{1-[2-methyl-4-(methylthio)-quinolin-3-yl]propan-2-ylidene}hydrazinocarbothioamides substituted in the benzene ring. The synthesis was conducted using readily available and non-toxic starting materials, ensuring a practical and accessible methodology. The results of this work may serve as a foundation for further studies aimed at exploring the biological and applied potential of these compounds.

Conformational Preference of Oxybis(methylene-1,3-dioxane-5,5-diil)dimethanol in Solvents of Various Nature
Аннотация
The conformational preference of oxybis(methylene-1,3-dioxane-5,5-diyl)dimethanol in various solvents was studied by NMR. According to the data of two-dimensional spectroscopy (NOESY), the bis(chair) form with diaxial oxymethyl groups is dominated in С6D6 and CDCl3, while the form with axial and equatorial oxymethyl groups at С5 and С5' atoms of the ring is dominated in DMSO-d6 and CD3CN solvents. The results of computer simulation of the conformational transformation of molecules of the studied diformal within the DFT approximation PBE/def2-SVP in these solvents (cluster model) are in complete agreement with the NMR results. It is shown that the optimal number of solvent molecules in the nearest solvate shell of the studied diformal varies from five to seven depending on the nature of solvent.
