Аннотация: The three-component synthesis of 7-substituted 6-ethoxycarbonyl-5-methyl-4,7-dihydroazolo[1,5-a]pyrimidines was carried out for the first time by the reactions of aminoazoles (3-aminopyrazole, 3-amino-1,2,4-triazole, or 5-aminotetrazole) with acetoacetic ester and aliphatic, aromatic, or heteroaromatic aldehyde.??

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.

Аннотация: O-Alkylation of 2-acetylphenols with ?,?-dichloro derivatives of oligoethylene glycols in the presence of KOH and Al2O3 in DMF gave the corresponding podands. Their condensation with ethyl trifluoroacetate afforded fluorine-containing bis(?-diketones) with the aryl fragments linked by conformationally flexible polyether spacers

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
