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.

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.

ACID-BASE PROPERTIES -- CATALYSIS -- COMPOSITE -- SILICA -- SPECIFIC SURFACE AREA -- ZIRCONIA
Аннотация: Using coprecipitation, a sol–sol method, and molecular layering, we have synthesized SiO2–ZrO2 composites with SiO2 : ZrO2 ratios from 1 : 1 to 9 : 1 and a large specific surface area, which increases with growth silicon-containing component concentration. Using adsorption of Hammett indicators, we have assessed the concentration of acid–base centers in the pK range 1.3–9.6, which has been shown to vary from 68 to 160 μmol/g. Elemental analysis and IR spectroscopy data have demonstrated the presence of not only water but also nitrate ions and carbon dioxide on the surface of the samples. It has been shown that the use of nanoparticulate SiO2–ZrO2 oxides as heterogeneous catalysts—promoters for (2S,4R)-4-hydroxyprolyl-(S)-1-phenylethylamine trifluoroacetate, a chiral inducer in the asymmetric Biginelli reaction, makes it possible to raise ee (enantiomeric excess) from 39 to 68% and the reaction yield from 29 to 55%.

    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.

    Stereoselective synthesis of dihydropyrimidinethione podand in the presence of L-proline or 4-hydroxy-L-proline and metal nitrates / E. S. Filatova, O. V. Fedorova, I. G. Ovchinnikova [et al.] // Russian chemical bulletin. - 2022. - Vol. 71, № 7. - P1506-1513
Рубрики: ХИМИЧЕСКИЕ НАУКИ
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.
