BIGINELLI REACTION -- PHENYLETHYLAMINE -- ALUMINUM OXIDES
Аннотация: The asym. Biginelli reaction was investigated in the presence of N-​[(2S,​4R)​-​4-​hydroxyprolyl]​-​(S)​-​1-​phenylethylamine as chiral inducer and silicon, titanium or aluminum oxides (individual and mixed, bulk and nanosized) as heterogeneous catalysts. The synthesis of Et (4R)​-​6-​methyl-​2-​oxo-​4-​phenyl-​1,​2,​3,​4-​tetrahydropyrimidine-​5-​carboxylate from benzaldehyde, urea and Et acetoacetate has been described. It has been shown that all studied oxides improve chemo- and stereoselectivity of the Biginelli reaction.

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 effect of nanosized metal oxides on the regio- and stereoselectivity of the multicomponent Biginelli reaction and the reaction mechanism under conditions of heterogeneous catalysis were studied. It was found that the considerable activation of reagents occurred on the surface of metal nanooxides. The Biginelli reaction occurred by two mechanisms: a carbocationic mechanism took place along with the generally accepted mechanism (through the N-acyliminium ion). Nanosized metal oxides in the presence of chiral inductors increased the regio- and stereoselectivity of the Biginelli reaction

METAL OXIDES -- HANTZSCH REACTION -- ALUMINUM OXIDES
Аннотация: The effect of nanosized copper and aluminum oxides, which have a higher sorption capacity than that of bulk samples, on the Hantzsch reaction was studied. The adsorption of starting benzaldehydes and ethyl acetoacetate on the surface of copper and aluminum nanooxides resulted in the activation of these molecules and accelerated the Hantzsch reaction. In addition, considerable activation of ammonia and intermediates (chalcone and enamine) on the surface of aluminum nanooxide facilitated an increase in the rate and selectivity of the process. The experimental results were used to develop a one-pot method for the preparation of nifedipine and nitrendipine

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.

    Features of a multicomponent biginelli reaction involving 3-oxobutanoyl-containing podands, aromatic aldehydes, and 1,2,4-triazol-3-amine / E. S. Filatova, O. V. Fedorova, K. A. Chistyakov [et al.] // Chemistry of heterocyclic compounds. - 2020. - Vol. 56, № 1. - P88-91

DIHYDROPYRIMIDINE -- MONOSUBSTITUTED PODAND -- PODAND -- TRIAZOLO[1,5-А]PYRIMIDINE -- TRIAZOLO[4,3-А]PYRIMIDINE -- TUBERCULOSTATIC ACTIVITY
Аннотация: [Figure not available: see fulltext.] A reaction of 3-oxobutanoyl-containing podands with thiophene-2-carbaldehyde (or benzaldehyde) and 3-amino-1,2,4-triazole gave podands featuring a 4,7-dihydro[1,2,4]triazolo[1,5-а]pyrimidine motif. It was established that the process was accompanied by the formation of [4,3-а]-isomers, which occurred in a slight excess during the synthesis of a podand containing a phenyl group at position 7 and, on the other hand, were observed as the minor products during the synthesis of podands bearing a thiophen-2-yl substituent. Trace amounts of monosubstituted podands were also detected, containing a free hydroxy group along with the triazolodihydropyrimidine pharmacophore.

Аннотация: Fluorinated enaminoketones, a new type of ligands, bearing two independent coordination centers (polyether's and fluorinated enaminoketones fragments) have been obtained. The crystal structure of the Cu(II) complex of 1,5-bis-[2-(4`,4`,4`-trifluoro-1`-methyl-3`oxo-but-1`-enylamino)-phenoxy]-3-oxapentane (10) has been elucidated by X-ray crystallography. The results obtained show that the complex 10 consists of two crystallographically independent molecules C26H24CuF6N2O5 (A and B), and the metal atom in the complex 10 has four-coordinated arrangement, as a polyhedron with a distorted square with two nitrogen and two oxygen atoms located in corners.
