    Усовершенствованный синтез билдинг-блоков для получения краун-эфиров c пиридиновыми или пиперидиновыми фрагментами = Convenient synthesis of building-blocks for pyridine/piperidine-decorated crown ethers / М. Б. Навроцкий, Е. Б. Горбунов, А. С. Бабушкин, Е. А. Ручко, Г. Л. Русинов, В. Н. Чарушин, И. А. Новаков // Макрогетероциклы. - 2014. - Т. 7. - С. 18-22. - Библиогр.: с. 22 (19 назв)

Дескрипторы: 2-VYNYLPYRIDINE -- EPOXIDATION -- PIPERIDINE
Аннотация: A convenient way to 1-(pyridin-2-yl)ethan-1,2-diol, 2-(oxiran-2-yl)pyridine and two diastereomeric forms of 1-(piperi-din-2-yl)ethan-1,2-diol, valuable building-blocks for the synthesis of functionalized crown ethers, has been developed. It is based on the Wagner oxidation or NBS-mediated epoxydation of 2-vinylpyridine, and the Schwenk-Papa reduction of 1-(pyridin-2-yl)ethan-1,2-diol, accompanied by fractional crystallization of a diastereo-meric mixture of the target produc

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

    Synthesis of novel [1,2,4]triazolo[1,5-b][1,2,4,5]tetrazines and investigation of their fungistatic activity / A. V. Korotina, S. G. Tolshchina, R. I. Ishmetova [et al.] // Beilstein Journal of Organic Chemistry. - 2022. - Vol. 18. - P243-250
Рубрики: ХИМИЧЕСКИЕ НАУКИ
Аннотация: A series of novel [1,2,4]triazolo[1,5-b][1,2,4,5]tetrazines has been synthesized through oxidation reaction of the corresponding 3,6-disubstituted 1,2,4,5-tetrazines bearing amidine fragments. It is shown that the heterocyclic systems obtained can be modified easily at C(3) position in the reactions with aliphatic alcohols and amines. Also, the reactivity of [1,2,4]triazolo[1,5-b][1,2,4,5]tetrazines towards CH-active compounds has been studied. The obtained triazolo[1,5-b]annulated 1,2,4,5-tetrazines proved to be active in micromolar concentrations in vitro against filamentous anthropophilic and zooanthropophilic dermatophyte fungi (Trichophyton, Microsporum and Epidermofiton), which cause skin and its appendages (hair, nails) diseases.

THIOPHENES -- 3-BENZOYLCOUMARINS -- Lewis acid
Аннотация: 3-Benzoyl-4-(thien-2-yl)coumarins have been obtained in good yields according to the SNH addition–oxidation protocol, involving the diastereoselective addition of thiophenes at C-4 of 3-benzoylcoumarins under BBr3 catalysis, followed by oxidation of the intermediate 3,4-trans-3-benzoyl-4-(thien-2-yl)-3,4-dihydrocoumarins with DDQ. This two-step procedure can be regarded as nucleophilic substitution of hydrogen (SNH) on the heterocyclic ring of coumarins

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.

5,11-DIHYDROINDOLO[3,2-B]CARBAZOLES -- 2-ARYLGLY-OXALS -- ACYLATION
Аннотация: An efficient approach for the double acetylation of 5,11-dihexyl- 6,12-di(hetero) aryl-substituted 5,11-dihydroindolo[3,2-b] carbazoles with acetic anhydride in the presence of boron trifluoride etherate has been developed, thus affording the corresponding 2,8-diacetyl derivatives in good yields. A similar acylation has been shown to occur by the reaction of anhydrides of other carboxylic acids. Oxidation of the obtained 2,8-diacetyl derivatives with selenium dioxide takes place on heating or under microwave irradiation, thus resulting in the formation of the corresponding 2,8-diglyoxals. The latter proved to react with aromatic o-diamines to afford new indolo[3,2-b] carbazoles bearing quinoxalinyl fragments at C-2 and C-8. Major optical properties of quinoxaline- containing indolo[3,2-b] carbazoles have been measured.
