NANOOXIDE TiO2–SiO -- BIGINELLI REACTION -- ASYMMETRIC CATALYSIS
Аннотация: The method for immobilization of chiral molecules (menthol and proline derivatives) on the mixed nanooxide TiO2–SiO2 surface has been developed. The synthesized nanocomposites were used as catalysts of the Biginelli reaction. It was shown that inactive chiral molecules, when covalently bonded to the nanooxide surface, acquired properties of a chiral inducer in the asymmetric Biginelli reaction.

ACETOACETAMIDE-CONTAINING PODANDS -- DIHYDROPYRIMIDINE-CONTAINING PODANDS -- ACETYLKETENE
Аннотация: Reactions of aliphatic aminopodands having different length of the polyether chain with acetoacetic ester and 2,2,6-trimethyl-4H-1,3-dioxin-4-one were studied. The interaction of aminopodands with acetoacetic ester in toluene upon sonication (60A degrees D) or heating (90A degrees D) gave podands with terminal aminocrotonate fragments. The use of dioxinone at the same temperature allowed to transform aminopodands into aliphatic acetoacetamide-containing podands. An asymmetric podand with 2-pyridone fragment was isolated as byproduct from the reaction of dioxinone with 1,5-diamino-3-oxapentane. A three-component Biginelli reaction of acetoacetamidecontaining podands with benzaldehyde and urea in the presence of catalytic amounts of polyphosphoric acid immobilized on nanosized TiO2-SiO2 oxide surface enabled the synthesis of podands with 1,4-dihydropyrimidin-2-(1De)-one fragments.

It has been shown that the ability of Fe@C-dibenzocrown ether composites for sorbtion of Yb3+ cations from 0.1 M hydrochloric acid solutions increased from 0 to 90.9-100 %, relative to dibenzocrown ether

Аннотация: A new type of intramolecular cyclization of 1,5-bis[2-(E-3-oxo-3-phenylprop-1-enyl)-phenoxy]-3-oxapentane with 3-aminotriazole promoted by potassium ions was discovered. A cascade mechanism for the formation of crownophane with 4,7-dihydro[1,2,4]triazolo[1,5-a]-pyrimidine fragment was suggested. Effects of oligooxyethylene fragment of the chalcone podand and acid-base catalysis on the selectivity of the cyclocondensation processes and degree of oxidation of triazolopyrimidine fragments were studied. The product structures were confirmed by IR, 1H and 13C NMR spectroscopy and X-ray diffraction study

SOL-GEL METHOD -- ZIRCONIUM OXYCHLORIDE -- SILICA-ZIRCONIA XEROGELS
Аннотация: The composite silica-zirconia xerogels have been prepared via sol-gel method using zirconium oxychloride, oxynitrate, acetate and sodium silicate as the precursors. The prepared materials have been characterized using FTIR, TG/DTA, EDX and surface area analyses. It has been established that surface area of silica-zirconia xerogels significantly depends on the zirconium source, but phase transitions and structural features of the xerogels seem to be unaffected by the choice of the zirconia precursor. Prepared xerogels increase the activity of chiral inductor in the asymmetric Biginelli reaction. The anion of the zirconium salt adsorbed on the surface of the synthesized material and the presence of Si-O-Zr heterolinkages determines the reaction yield. The highest chemo- and enantioselectivity towards formation of ee isomer have been provided by the catalyst prepared from zirconium oxychloride.

Аннотация: The asymmetric Biginelli reaction involving a 3-oxobutanoyl-containing podand, benzaldehyde, and thiourea was studied using secondary amines as a chiral inductor, Brönsted acid as a catalyst, and metal salts (especially metal nitrates) as an additive of asymmetric catalysis (AAC) was studied. The tuberculostatically active dihydropyrimidine-thione-containing podand was synthesized with an enantiomeric excess of 57% in the presence of 4-hydroxy-L-proline. In the presence of metal nitrates, the influence of the ionic radius of the cation on the enantioselective excess of the reaction under study was observed, which made it possible to propose a possible mechanism of chiral induction controlled by the complexing ability of the initial β-ketoester-containing podand with metal ions and coordination of the reagents in the transition states.

Аннотация: Individual and mixed oxides of Zn, Mg, Si, and Ti modified with L-proline during their solgel synthesis have been obtained. The IR spectra of these oxides studied in detail show changes in the vibrational band parameters of the siliconoxygen and metal–oxygen bonds. Enhancement of the amount of basic sites on the SiO2–TiO2 mixed oxide was found after removal of L-proline from the surface. The use of SiO2–Mg(OH)2* L-proline composite as a catalyst leads to an enhanced enantiomeric excess of some asymmetric Biginelli reaction products up to 18%.
