ХИМИЯ ЗЕЛЕНАЯ -- СИНТЕЗ ОРГАНИЧЕСКИЙ
Аннотация: After the appearance of the green chemistry concept, which was introduced in the chemistry vocabulary in the early 1990s, its main statements have been continuously developed and modified. Currently, there are 10–12 cornerstones that should form the basis for an ideal chemical process. This review analyzes the accumulated experience and achievements towards the design of chemical products and processes that reduce or eliminate the use or generation of hazardous substances. The review presents the views of leading Russian scientists specializing in various fields of this subject, including homogeneous and heterogeneous catalysis, fine and basic organic synthesis, electrochemistry, polymer chemistry, chemistry based on bio-renewable feedstocks and chemistry of energetic compounds and materials. A new approach to the quantitative evaluation of the environmental friendliness of processes developed by Russian authors is described.

    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.

ПОДАНД ДИГИДРОПИРИМИДИНТИОНСОДЕРЖАЩИЙ -- НИТРАТЫ МЕТАЛЛОВ -- СТЕРЕОСЕЛЕКТИВНАЯ РЕАКЦИЯ БИДЖИНЕЛЛИ
Аннотация: Исследована асимметрическая реакция Биджинелли с участием 3-оксобутаноилсодержащего поданда, бензальдегида и тиомочевины с использованием вторичных аминов в качестве хирального индуктора, кислоты Бренстеда, как катализатора и солей металлов (в особенности, нитратов металлов) в качестве добавки (additive of asymmetric catalysis, AAC). Туберкулостатически активный дигидропиримидинтионсодержащий поданд получен с энантиомерным избытком 57% в присутствии 4-гидрокси-L-пролина. В присутствии нитратов металлов отмечено влияние ионного радиуса катиона на величину энантиоселективного избытка исследуемой реакции, что позволило предложить возможный механизм хиральной индукции, регулируемый комплексообразующей способностью исходного β-кетоэфирсодержащего поданда с ионами металлов и координацией реагентов в переходных состояниях.

SUPPORTED IRIDIUM NANOPARTICLES -- N-ARYLHYDROXYLAMINE -- SEMI-HYDROGENATION
Аннотация: Polystyrene stabilized Iridium (Ir@PS) nanoparticles (NPs) as a heterogeneous catalyst have been developed and characterized by IR, UV–Vis, SEM, TEM, EDX and XRD studies. The prepared Ir@PS catalyst showed excellent reactivity for chemo- and regio-selective controlled-hydrogenation of functionalized nitroarenes to corresponding N-arylhydroxylamine using hydrazine hydrate as reducing source and environmentally benign polyethylene glycol (PEG-400) as green solvent. The present methodology was applied for vast substrate scope and found to be compatible with wide range of reducible functional groups. The reaction performed at 85 °C or ambient temperature and completed within 5–80 minutes. The catalyst can easily be filtered out from reaction mixture and reusable.

It was observed that maleimides also works moothly under this metal-free reaction condition. This present method implies the oxidative coupl in greaction through a one-stepprocess with the generationof CN and CS bonds.Various aromaticand aliphaticthiolsand amines provided the correspond ingthioaminated compounds in 62–88% yields.A plausiblere action path way has been predicted according to few control experiments.

CARBONYLATION -- SUZUKI-MIYAURA COUPLING -- TRANSITION-METAL CATALYSIS
Аннотация: Transition metals have been an indispensable component of modern catalysis and among these palladium is the top-ranked choice of chemists as a catalyst. After the several important developments of palladium catalysed C−C cross-coupling reactions, carbonylative transformations have been realised as an attractive post modification of these reactions. Carbonylative Suzuki-Miyaura coupling reaction is among such transformations for direct incorporation of CO fragment for the preparation of biaryl or aryl/alkyl ketones via transition-metal catalysis. Ketone functionality is basically a valuable building block having huge pharmaceutical and agrochemical applications. Moreover, carbonylative Suzuki-Miyaura coupling is also used in the synthesis of various natural bioactive molecules through the direct joining of molecular fragments via CO bridge. In this review, the past decade developments in the carbonylative Suzuki-Miyaura coupling reactions are documented in detail with modern approaches in transition-metal catalysis.

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%.

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.

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
