NITROGEN HETEROCYCLES -- FLUORINE -- OXYGEN HETEROCYCLES
Аннотация: New synthetic routes to trifluoromethylated N-heterocycles based on condensations of 2-methoxy-2-methyl-5-(trifluoromethyl)furan-3(2H)-one with bifunctional N-nucleophiles are described. For the first time, trifluoromethyl-containing pyrazoles, pyrazolines and isoxazolines bearing hydrazone or oxime groups could be obtained by a one-pot strategy based on reactions of 5-(trifluoromethyl)furan-3(2H)-one with two equivalents of the corresponding hydrazines or hydroxylamine in the presence of an acid. The interaction of furan-3(2H)-one with ureas proceeded under mild conditions to furnish 1H-furo[2,3-d]imidazol-2(3H)-one derivatives in good yield. Further, a trifluoromethyl-containing quinoxaline derivative was obtained by condensation of furan-3(2H)-one with ortho-phenylenediamine.

5,11-DIHYDROINDOLO[3,2-B]CARBAZOLES -- ACYLATION -- 2-ARYLGLYOXALS
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.

    New approach to biologically active indolo[2,3-b]quinoxaline derivatives through intramolecular oxidative cyclodehydrogenation / G. Sadykhov, D. V. Belyaev, M. G. Pervova [et al.] // ChemistrySelect. - 2022. - Vol. 7, № 18. - Pe202200497
Рубрики: ХИМИЧЕСКИЕ НАУКИ
Аннотация: A convenient synthetic protocol to antiviral agent B-220 and a series of similar indolo[2,3-b]quinoxaline derivatives has been developed. This synthetic approach is based on Buchwald-Hartwig cross-coupling and subsequent annulation by intramolecular oxidative cyclodehydrogenation. For the first time, 6H-indolo[2,3-b]quinoxaline amine derivatives were evaluated for antimycobacterial activity. The moderate bacteriostatic effect against Mycobacterium tuberculosis H37Rv was found. A plausible mechanism of antibacterial action was elucidated by the molecular docking.

    Push–pull derivatives based on 2,4'-biphenylene linker with quinoxaline, [1,2,5]oxadiazolo[3,4-b]pyrazine and [1,2,5]thiadiazolo[3,4-b]pyrazine electron withdrawing parts / E. V. Verbitskiy, Y. A. Kvashnin, G. L. Rusinov [et al.] // Molecules. - 2022. - Vol. 27, № 13. - Ст. 4250

Аннотация: A series of novel V-shaped quinoxaline, [1,2,5]oxadiazolo[3,4-b]pyrazine and [1,2,5]thiadiazolo[3,4-b]pyrazine push–pull derivatives with 2,4′-biphenylene linker were designed and their electrochemical, photophysical and nonlinear optical properties were investigated. [1,2,5]Oxadiazolo[3,4-b]pyrazine is the stronger electron-withdrawing fragment as shown by electrochemical, and photophysical data. All compounds are emissive in a solid-state (from the cyan to red region of the spectrum) and quinoxaline derivatives are emissions in DCM solution. It has been found that quinoxaline derivatives demonstrate important solvatochromism and extra-large Stokes shifts, characteristic of twisted intramolecular charge transfer excited state as well as aggregation induced emission. The experimental conclusions have been justified by theoretical (TD-)DFT calculations.
