Аннотация: For the first time, the direct C(sp(2))-H functionalization methodology has successfully been applied to cause nucleophilic modification of mono- and diazine-N-oxides with the 1,2-closo-carborane moiety. As a result of these cross-coupling reactions uncatalyzed by transition metals, a series of novel C-modified heterocyclic and open-chain (vinyl acetylene) carboranes have been obtained. Complexes of phenanthrolinyl-substituted omicron-carborane with Cu(II) of various architectures have been synthesized.

Аннотация: The behavior of 4-thienyl substituted pyrimidine ligands (L1-3) has been studied for the series of their reactions with various salts of 3d metals (Co, Zn, Ni, Cu) and platinoids (Pt, Pd). In particular, mononuclear Co(OTf)(2)(L1-3)(2)(H2O)(2)(MeCN)(2) (1), binuclear Co-2(Piv)(2)(L1-3)(4) (2a,b), Cu-2(Piv)(2)(L1-3)(2) (5a,b), heterometallic polynuclear Li2Co2(Piv)(6)(L1-3)(2) (4) and chelate [(L-1)Pd(OAc)](2) (6) complexes have been obtained. The structures of all complexes have been established by X-ray diffraction. Also magnetic properties of coordination compounds 1, 2, 4 and 5 have been studied in details. In particular, mononuclear Co(II) complexes I and 4 proved to exhibit paramagnetism with large positive zero-field splitting parameters. Dinuclear Co(II) complexes 2a,b show weak antiferromagnetic interactions. Dinuclear Cu(II) complexes 5a,b demonstrate strong antiferromagnetic superexchange interactions via four carboxylate bridges. The systems 2a,b and 5a,b are isolated as exchange coupled dimers

Аннотация: Triterpene derivatives with an α,β-alkenenitrile moiety in the five-membered ring A have been synthesized by nitrile anion cyclizations of 1-cyano-2,3-secotriterpenoids. Oxime-containing precursors, 2,3-secointermediates and five-membered ring A products of cyclizations were screened for in vitro antiviral activity against enveloped viruses – influenza A virus and human immunodeficiency virus type I (HIV-1). Lupane ketoxime and the 2,3-secolupane C-3 aldoxime which possess antiviral activities against both influenza A virus (EC50 12.9–18.2 μM) and HIV-1 (EC50 0.06 μM) were the most promising compounds.

Аннотация: The structures and characteristic features of the molecular packing patterns of complexes of pyridazines containing heterocyclic substituents and the carborane moiety with 2,3,5,6-tetrachlorohydroquinone (TCHQ) were investigated. It was shown that TCHQ can form supramolecular assemblies with carborane-containing substituted pyridazines. The stoichiometry and three-dimensional structures of these assemblies depend on the substituents in the pyridazine ring and are formed via O-H…N hydrogen bonding between TCHQ and heterocyclic molecules

A comparison is made of the nonbonding interactions of dihydrothiazoloquinolinium with atoms of the triiodide anion and complex polyiodide to show the crystal structure features attributed to the participation of molecular iodine.

Аннотация: The reactions of β-azolylenamines 1 with sulfonyl azides 2 in acetonitrile furnished 1H-4-(azol-5-yl)-1,2,3-triazoles 3 in yields of 52-93%. β-Benzoylenaminones and β-nitroenamine of type 1 also reacted with tosyl azide to form the same type of products 3, proving the generality and efficiency of the method for the synthesis of N-unsubstituted 1,2,3-triazoles. On the other hand, the reactions of 3-(1-aryl-1,2,3-triazol-5-yl)enamines with tosyl azide in the absence of a solvent afforded a mixture of (E)-1-dimethylamino-2-tosylaminoethenes 5 and N,N-dimethyl-N′- tosylformamidine 6 in yields of 40-50 and 20%, respectively. The formation of a variety of compounds from the reactions of enamines 1 with sulfonyl azides 2 is rationalized by the various possible transformations of the intermediate 5-dimethylamino-1,2,3-triazolines

Аннотация: New synthetic routes to trifluoromethylated N-heterocycles based on condensations of 2-methoxy-2-methyl-5-(trifluoromethyl)furan-3(2H)-one with bifunctional N-nucleophiles are described. For the first time, trifluoromethyl-containing pyrazoles, pyrazolines and isoxazolines bearing hydrazone or oxime groups could be obtained by a one-pot strategy based on reactions of 5-(trifluoromethyl)furan-3(2H)-one with two equivalents of the corresponding hydrazines or hydroxylamine in the presence of an acid. The interaction of furan-3(2H)-one with ureas proceeded under mild conditions to furnish 1H-furo[2,3-d]imidazol-2(3H)-one derivatives in good yield. Further, a trifluoromethyl-containing quinoxaline derivative was obtained by condensation of furan-3(2H)-one with ortho-phenylenediamine.
