A trifluoroacetic acid promoted step-economical one-pot approach to the synthesis of furo-fused quinoxalines/pyrazines by the reaction of 2,3-dichloroquinoxalines/pyrazines with alkynes is described. The reaction involves a selective in-situ Sonogashira coupling step and a hydroxylation followed by a metal-free 5-endo-dig cyclization. Preliminary experiments show that trifluoroacetic acid acts as a source of oxygen for the oxyarylation step, and isotopic labeling studies support the proposal that the mechanistic pathway involves activation of the alkyne by the acidic medium. Various kinds of substituents are tolerated, which should prove valuable for structural and biological investigations.

We’ll also look at important developments in the pharmaceutical industry because understanding organic chemistry is important in understanding health, medicine, the role of 63810-80-0, and how the biochemistry of the body works.name: 2,3-Dichloro-6,7-dimethylquinoxaline

Various oxepine and azepine fused N-heterocyclic derivatives were synthesized using a new and one-pot reaction of 2,3-dichloro quinoxaline/pyrazine with 2-(1H-indol-2-yl)phenol/aniline in the presence of 25 mol% FeCl3. The reaction proceeded via C-C bond followed by C-X (X = O or N) bond formation to construct the central 7-membered ring, affording the desired products in good yields. The structure assignment was confirmed by the single crystal X-ray analysis of a synthesized oxepine fused N-heterocycle derivative. Most of the synthesized compounds were found to be promising when tested for their anti-proliferative properties against cervical and breast cancer cell lines.

New Advances in Chemical Research, May 2021. In heterogeneous catalysis, catalysts provide a surface to which reactants bind in a process of adsorption. name: 2,3-Dichloro-6,7-dimethylquinoxaline, In a article, mentioned the application of 63810-80-0, Name is 2,3-Dichloro-6,7-dimethylquinoxaline, molecular formula is C10H8Cl2N2

The syntheses, characterizations, and substituent effects on the vase vs kite conformations of 1-17 are described. These compounds are assembled by two-step syntheses from resorcinol (or 2-substituted derivatives) and aldehydes to form octols 18-26 in high yields, followed by 4-fold bridging reactions with quinoxalines 27-29 or pyrazine 30. In the crystal structure of 3-2CH2Cl2, one CH2Cl2 is enclosed in the vase cavity, while a second CH2Cl2 is found surrounded by the four (CH2)4Cl groups. When the 2-position of resorcinol is hydrogen, only the vase form of the cavitands exists at 25 C or higher when quinoxaline bridged, as in 1-7, and at all available temperatures when pyrazine bridged, as in 13. The R and B groups of 1-7 can be varied to control solubility and cavity size without greatly affecting the vase-kite structures. When the 2-position of resorcinol is occupied by a methyl, an ethyl, or a bromine, as in 14-17, only the kite conformation is observed at all available temperatures. When the 2-position is hydrogen and the system is quinoxaline, only the kite conformer is observed at temperatures below -50 C. When the 2-position is CH3, the kite conformer equilibrates with its dimer. When the 2-position is CH3CH2, as in 17, the kite conformer does not form a dimer. The kite C2v, structures under pseudorotation and also dimerize when they contain 2-methylresorcinyl groups to give dimers of D2d symmetry. In some systems, these processes could be differentiated by use of variable-temperature 1H NMR spectra.

A series of five 6,7-disubstituted 1,4-dihydro-2,3-quinoxalinediones was prepared, two of which are known microbial flavin metabolites and three of which are potential flavin metabolites. Four of the five compounds inhibited specific binding of [3H]-amino-3-hydroxy-5-methyl-4-isoxazolepropanoic acid ([3H]AMPA), [3H]kainic acid, and [3H]6-cyano-1,4-dihydro-7-nitro-2,3- quinoxalinedione ([3H]CNQX) in rat brain homogenate fractions, with IC50 values in the low micromolar range (the fifth compound competed only with [3H]CNQX). Two of the compounds were moderately potent AMPA antagonists in an in vitro functional test.

The preparation and biological evaluation of a series of 4-alkylamino-1-hydroxymethylimidazo[1,2-a]quinoxalines as adenosine A 1 receptor antagonists are described. 4-Cyclopentylamino-7,8- dichloro-1-hydroxymethylimidazo[1,2-a]quinoxaline shows potent adenosine A 1 receptor inhibitory activity, having Ki = 7 nM. A series of 4-alkylamino-1-hydroxymethylimidazo[1,2-a]quinoxalines have been synthesized and evaluated for their adenosine A1 receptor inhibitory activity in the radioligand binding assays. The compounds were tested for the inhibition percent (IP) and the affinity toward A1AR (Ki) that IP were more than 90% in the nanomolar range. 4-Cyclopentylamino-7,8-dichloro-1- hydroxymethylimidazo[1,2-a]quinoxaline 18 is the most potent compound in this series, having Ki = 7 nM, which is remarkably higher than that of IRFI-165 (Ki = 48). 1-Hydroxymethyl groups of the tricyclic heteroarmatic compounds displayed the potent affinities toward A1AR.

An inexpensive, practical and one-pot method has been developed for the synthesis of quinoxalines fused with pyrano[3,4-b]indole, the central core of Lamellarin D. The methodology involved construction of the central pyranone ring via an AlCl3-mediated heteroarylation-cyclization method. A number of compounds were prepared using this methodology, some of which were converted to the corresponding indol-3-ylquinoxaline derivatives. Several of the pyrano[3,4-b]indole fused quinoxalines showed promising growth inhibition of cervical and lung cancer cells and good interactions with topoisomerase I in silico.

Compounds 13 display long-wavelength absorption maxima in the green (1) and yellow (2 and 3) to give intensely coloured red and purple solutions, respectively. Bis(2,2?-bipyridyl)ruthenium(ii) and bis(4,4?- dimethyl-2,2?-bipyridyl)ruthenium(ii) complexes were prepared in moderate to good yields, characterized by NMR spectroscopy and mass spectrometry, and studied by cyclic voltammetry and absorption spectroscopy. Copper(ii) and silver(i) nitrate complexes of the ligands were prepared and complexes [Cu(NO3)2(1)], [Cu(NO3)2(2)] 2, and [Ag(NO3)(3)2] were characterized by X-ray crystallography. These structures revealed the planar nature of the ligands and confirmed the proposed chelating mode.
