, p. 11873 - 11883 (2015/02/19)
A new synthetic strategy of tandem N-aroylmethylation-nitro reduction-cyclocondensation has been developed for the first and generalized regioselective synthesis of 2-aryl quinoxalines adopting "all water chemistry." Water plays the critical role through

A novel method for the synthesis of quinoxalines via transition-metal-free cyclization of o-phenylenediamine and arylacetaldehyde in a one-pot procedure has been developed. In this process, an inorganic base (K2CO 3) is the only reagent required, and it proceeds smoothly in the absence of adding transition metal catalysts. The reaction appears to be very general and suitable for the construction of a variety of quinoxalines. Georg Thieme Verlag Stuttgart. New York.
Regioselective Suzuki-Miyaura cross-coupling reactions of 2,6-dichloroquinoxaline
Ali, Iftikhar,Siyo, Baraa,Al-Soud, Yaseen,Villinger, Alexander,Langer, Peter
experimental part, p. 1637 - 1646 (2012/06/30)
A variety of mono- and diarylated quinoxaline derivatives were prepared by site-selective Suzuki-Miyaura cross-coupling reactions of 2,6- dichloroquinoxaline. The selectivity is controlled by electronic parameters. Georg Thieme Verlag Stuttgart · New York
A convenient approach to the synthesis of quinoxalines from isoxazolones and 1,2-diaminobenzenes
Rao, M Hanmantha,Reddy, A Pandu Ranga,Veeranagaiah, V
, p. 88 - 91 (2007/10/02)
2-Aryl-6,7-(un)substituted-quinoxalines (3a-t) and 2-arylbenzimidazoles (4a-t) have been obtained by condensation of 3-aryl-5(4H)-isoxazolones (1a-e) and 4-(un)substituted-1,2-diaminobenzenes (2a-d) under neutral conditions.The mechanism of their formation is illustrated.
