Abstract:

We report a ligand-free chromium(II)-catalyzed amination reaction of various N-heterocyclic chlorides. CrCl2 regioselectively catalyzes the reaction of chloropyridines and dichloropyridines, dichloroquinolines, dichloroisoquinolines and dichloroquinoxalines with a range of aliphatic, allylic, benzylic and saturated (hetero)cyclic magnesium amides in the presence of lithium chloride as additive. The reactions were performed at 50 °C in THF and led to the desired aminated products in 56–96% yield.

A synthesis of novel hexacyclic bis-benzimidazoles 6 starting from 2,3-diarylamino-quinoxalines via an oxidative cyclization cascade is described. These very stable and high-melting derivatives are featured by their strong fluorescence in the blue region of the visible spectrum. The cyclization reaction between 2,3-dichloroquinoxaline and 1,2-phenylenediamine did not lead to derivatives of type 6. In this case, only fluoflavine 7 was isolated quantitatively.

Some examples are reported that involve the formation of cyclic benzodioxin and phenoxathiine derivatives from 4,5-difluoro-1,2-dinitrobenzene, racemic quinoxaline thioethers, and sulfones from 2,3-dichloroquinoxaline and (2-aminophenylethane)-2,5-dithiophenyl-4-nitrobenzene from 1-(2-aminophenylethane)-2-fluoro-4,5-dinitrobenzene. Four X-ray single-crystal structure determinations are reported, two of which show short intermolecular N–O…N “π hole” contacts.

Abstract:

Abstract Quinoxalines are a family of nitrogen-based heterocyclic compounds that have garnered much interest because of their wide range of applications. 2,3-Dichloroquinoxaline is an aromatic molecule that frequently serves as a synthetic intermediate in materials science, pharmaceuticals, and organic chemistry. 1,3-Dithiolo[4,5-b]quinoxaline derivatives 8a–c and thiazolo[4,5-b]quinoxaline derivatives 11a,b were synthesized by the reaction of 2,3-dichloro-6-sulfonyl quinoxaline derivative 5 with 1,3-binucleophiles. Moreover, 1,3-dithiolo[4,5-b]quinoxalin2-ylidene derivatives 8a–c were obtaine
