    Expanding 1,2,4-triketone toolbox for use as fluorinated building blocks in the synthesis of pyrazoles, pyridazinones and β-diketohydrazones / Y. O. Edilova, Y. V. Burgart, V. I. Saloutin [et al.] // Journal of fluorine chemistry. - 2022. - Vol. 253. - Ст. 109932

Аннотация: Fluorinated lithium β-diketonates bearing a methyl acetal group behave in the condensation reactions with hydrazines as trielectrophilic building blocks for the preparation of pyrazoles, pyridazinones and β-diketohydrazones. For the first time, solvent-induced regioisomeric and heterocyclic ring size-controlled formation was observed for 1,2,4-triketone analogues. Fluoroalkylated acetyl NH-pyrazoles or substituted 5-RF-pyrazoles were obtained from the acid-catalyzed cyclocondensation of lithium β-diketonates with (aryl)hydrazines in ethanol. In methanol solvent acetyl-containing 3-CF3-pyrazoles were isolated because of inverse nucleophilic attack of arylhydrazines. The use of aprotic acetonitrile in the condensation resulted in regioselective trifluorinated pyridazinones and fluorinated β-diketohydrazones formation via initial acetal fragment interaction with N,N-dinucleophile.

GROWTH-FACTOR RECEPTOR -- POTENT EGFR INHIBITORS -- TYROSINE KINASE INHIBITORS
Аннотация: Scieces of data on the synthesis and antitumour activity of 4-aminoquinazolines are summarized and analyzed. Key methods for the synthesis of these compounds are considered, primarily cyclocondensation of carboxylic acid derivatives, as well as the oxidation of quinazolines and the cyclization of disubstituted thioureas. Improvements of synthetic schemes for erlotinib, gefitinib and lapatinib, which are the best-known pharmaceuticals based on compounds of the title class, are also considered. Synthetic strategies and biological activities for new 4-aminoquinazoline derivatives that are EGFR-tyrosine kinase inhibitors, multiactive compounds, and labelled compounds for use as positron emission tomography (PET) imaging agents are discussed.

1,3,4-THIADIAZINE -- CYCLOCONDENSATION -- NONENZYMATIC GLYCOSYLATION OF PROTEINS -- THIOSEMICARBAZIDES
Аннотация: A series of new 1,3,4-thiadiazines with cycloalkylamino (cyclopropylamino, cyclobutylamino, cyclopentylamino, cyclohexylamino) groups were synthesized via cyclocondensation of α-haloacetophenones with thiosemicarbazides containing 4-cycloalkyl groups. Five of the synthesized compounds showed the capability to inhibit nonenzymatic glycosylation of proteins in vitro in a model system. The obtained test results allowed compounds containing cyclopropylamino residues (LT-1a and LT-1d) to be recommended for further in vivo testing

ALIPHATIC AND AROMATIC AMINES -- ETHYLENEDIAMINE -- FORMALDEHYDE
Аннотация: 6-Polyfluoroalkyl-2-thiouracils react with formaldehyde and primary amines in EtOH (MeCN) at 2-mercapto and 3-amino groups to yield pyrimido[2,1-b][1,3,5] thiadiazines via the multicomponent double Mannich reaction. The structure of 3-benzyl-8-nonafluorobutyl-3,4-dihydro-2H,6H-pyrimido[2,1-b][1,3,5] thiadiazin-6-one was studied by the X-ray diffraction analysis. The use of ethylenediamine in these reactions yields 3,3′-ethane-1,2-diyl- bis(pyrimido[2,1-b]thiadiazinone) as a result of the bis-double Mannich cyclocondensation. 8-Polyfluoroalkyl-pyrimido[2,1-b]thiadiazines exhibit weak tuberculostatic activity

TEMPLATE SYNTHESIS -- CHALCONE PODAND -- CROWN ETHERS
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

Аннотация: Previously unknown products of the cyclocondensation of 1,1,1-trifluoro-2,4-pentanedione with triaminoguanidine and hydrazine derivatives of 1,2,4,5-tetrazine have been obtained. 5-Hydroxy-5-trifluoromethylpyrazoline substituents formed on the tetrazine ring were dehydrated under the action of trifluoroacetic anhydride. A comparison has been carried out of the reactivity of 5-trifluoromethylpyrazolyl-substituted 1,2,4,5-tetrazines and their unfluorinated analogs in nucleophilic substitution and [4 + 2] cycloaddition reactions

Аннотация: The condensation of 4-hydroxy-3,5-diphenyl-2-phenyliminothiazolidine with 5-fluoro-4-morpholino- and 5-fluoro-4-(4-methylpiperazino)-1,2-phenylenediamines leads to region-isomeric thiazolo[3,4-a]quinoxalines differing in substituents in positions 7 and 8 of the benzene ring. From the ratio of isomers formed it follows that the mesomeric effect of a fluorine atom in 1,2-phenylenediamines is comparable with the influence of an aminosubstituent

Аннотация: A new method was developed for the construction of tetra- and pentacyclic fused systems based on sigma(H)-adducts of 6-nitro-1,2,4-triazolo[1,5-a]pyrimidine with pi-excessive heteroaromatic compounds. The method involves the reduction of the nitro group accompanied by the aromatization of the dihydropyrimidine ring and followed by the cyclocondensation of the amino derivative with aldehydes
