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: The kinetic resolution of racemic heterocyclic amines via acylation with N-tosyl-(S)-prolyl chloride was systematically investigated. It was established that racemic mixtures of aromatic amines could be resolved with high efficiency, while the acylation of 2- and 3-methylpiperidines occurred with low diastereoselectivity. A method for the preparation of enantiomerically pure (3 R)-7,8-difluoro-3-methyl-3,4-dihydro-2 H-[1,4]benzoxazine was developed

It has been shown that the presence of fluorine atoms in the aromatic fragment of a heterocyclic amine results in the increasing stereoselectivity of acylation with (S)-naproxen acyl chloride and in a decrease in the efficiency of acylative kinetic resolution using N-phthaloyl-(S)-amino acyl chlorides. A method for the preparation of enantiopure (S)-6-fluoro-2-methyl-1,2,3,4-tetrahydroquinoline (ee >99%) was developed

Аннотация: The comparative X ray diffraction study of racemic and (S) enantiomer of 7,8 difluoro 3 methyl 2,3 dihydro 4H [1,4]benzoxazine was carried out. The both forms of benzoxazine are crystallized in the orthorhombic crystal system, the (S) enantiomer is crystallized in the chiral space group P212121, while the racemate is crystallized in the centrosymmetric Pbca space group. The bond lengths and bond and torsional angles in the both molecules are almost equal. The packing of the racemate is characterized by a closer interaction of polar NH...О groups.

KINETIC RESOLUTION -- ACYLATION -- AMINES -- AMIDES
Аннотация: Acylative kinetic resolution of racemic amines occupies a highly important place among the methods for preparation of enantio enriched or pure amines. Nonenzymatic acylative kinetic resolution is usually carried out in the presence of chiral acyl-transfer catalysts or under the action of chiral enantio- or diastereoselective resolving agents. Recently, this line of investigations has been rapidly developed and very interesting results of design and synthetic application of both new catalysts and chiral acylating agents have been obtained. This microreview summarizes the recent advances in this area.

Аннотация: Kinetic resolution of racemic 3 methyl 2,3 dihydro 4H [1,4]benzoxazines in the reaction with chiral 2 arylpropionyl chloride predominantly yielded R*,R* diastereomers. Ibuprofen acyl chloride as acylating agent was found to be more selective and sensitive to the changes in the reaction temperature as compared to naproxen acyl chloride and 2 phenylpropionyl chloride

Аннотация: The fundamental possibility of acylative kinetic resolution of racemic heterocyclic amines was demonstrated by the example of all-cis-5-(4-bromophenyl)-4-tert-butoxycarbonyl-2-methoxycarbonylpyrrolidine. Individual enantiomers (ee >99%) were obtained in high yields via preparative chiral HPLC

    Modification of chemically and physically obtained Fe3O4 magnetic nanoparticles with L-Lys for cell labeling / A. M. Demin, O. F. Kandarakov, A. S. Minin [et al.] // Russian chemical bulletin. - 2021. - Vol. 70, № 6. - P1199-1208
Рубрики: ХИМИЧЕСКИЕ НАУКИ
Аннотация: Peculiar features of the modification of Fe3O4 magnetic nanoparticles (MNPs) obtained by co-precipitation from solutions of FeII and FeIII salts (10-nm MNPs) and by the gas-condensation method (30-nm MNPs) with 3-aminopropylsilane and then with L-lysine were studied. The chemically obtained MNPs possess more pronounced hydrophilic properties and therefore readily form stable aqueous colloidal solutions and can be loaded with a larger amount of L-Lys. However, samples based on the physically obtained MNPs were characterized by more efficient internalization and longer retention times by the NIH 3T3 cells. The results obtained can be used in the design of novel nanomaterials for magnetic cell labeling.
