Chemo-enzymatic cascade processes are invaluable due to their ability to rapidly construct high-value products from available feedstock chemicals in a one-pot relay manner. Product Details of 6344-72-5, In a article, mentioned the application of 6344-72-5, Name is 6-Methylquinoxaline, molecular formula is C9H8N2

An efficient and inexpensive sulfated polyborate catalyst was applied for the rapid synthesis of quinoxaline derivatives from various substituted o-phenylenediamines and 1,2-diketones/alpha-hydroxy ketones using sulfated polyborate is described. The catalyst has the advantage of Lewis as well as Bronsted acidity and recyclability without significant loss in catalytic activity. The key advantages of the present method are high yields, short reaction times, solvent-free condition, easy workup, and ability to tolerate a variety of functional groups, which give economical as well as ecological rewards.

Electric Literature of 2213-63-0, New research progress on 2213-63-0 in 2021. Chemistry is a science major with cience and engineering. The main research directions are chemical synthesis, preparation and modification of special coatings, and research on the structure and performance of functional materials.2213-63-0, Name is 2,3-Dichloroquinoxaline, molecular formula is C8H4Cl2N2. In a article，once mentioned of 2213-63-0

Cyclic voltammetry and controlled-potential electrolysis have been employed to examine the electrochemical behavior of some mono- and dichlorinated pyrazines, quinoxalines, and pyridazines at carbon and mercury cathodes in either acetonitrile or dimethylformamide containing a tetraalkylammonium salt. Unsubstituted pyrazine and pyridazine each exhibit a single reduction wave, whereas unsubstituted quinoxaline shows three cathodic waves. For the chlorinated compounds, an additional wave is seen for the reduction of each carbon-chlorine bond. Depending on the potential of the cathode, bulk electrolyses of dichlorinated pyrazines or quinoxalines afford either the monochlorinated or fully dechlorinated product, whereas the monochlorinated analogues undergo reduction to the dechlorinated species. Electrolyses of chlorinated pyridazines give dark colored solutions, but the products (apparently polymeric) cannot be detected or identified by means of conventional GC, GC-MS, and HPLC techniques.

We have developed a novel fluorescent scaffold 4 which is a 9-nitro-2,3-dihydro-1H-pyrimido[1,2-a]quinoxalin-5-amine derivative from the reaction between di-tert-butyl but-2-ynedioate and a quinoxaline molecule containing a dimethyl amine side tail in high yield. The synthesis of scaffold 4 involves an sp3 C-N bond cleavage mechanism which is not very common. The scaffolds 4 is emissive in the visible range lambdaem ? (517-540) nm with large stokes shifts (5005-6378) cm-1 in ethanol. Laser confocal microscopy of the live HepG2 cells treated with compound 4f shows that it can be used for live cell imaging in nanomolar concentrations.

2-Alkynyl-3-chloroquinoxalines are prepared from 2,3-dichloroqionoxaline and alk-1-ynes: use of 2-methylbut-3-yn-2-ol, and the removal of acetone with base, yields 2-chloro-3-ethynylqionoxaline.The chloroalkynes are readily converted into pyrrolo- and thieno<2,3-b>qionoxalines. 2-Chloro-3-phenylethynylquinoxaline with potassium hydroxide gives 2-phenylfurano<2,3-b>quinoxaline but other furano-compounds could not be prepared. 2-Chloro-3-(3-hydroxy-3-methylbut-2-ynyl)quinoxaline with ethanolic sodium ethoxide yields 2H-2,2-dimethyl-3-ethoxypyrano<2,3-b>quinoxaline.When 2-ethynyl- or 2-chloro-3-ethynylqionoxaline is heated with morpholine and sulphur, 2-morpholinothieno<2,3-b>quinoxaline is obtained.The structures of these compounds are established by spectroscopic methods.
