A novel and efficient approach to the C(sp2)–H/C(sp3)–H oxidative coupling of quinoxalin-2(1H)-ones with methylarenes by using CuI as catalyst is reported. Various substrates were well tolerated in this methodology and the desired products were given in moderate-to-good yields. This reaction features good functional group compatibility and broad substrate scope.

An efficient, photoredox-catalyst-free radical alkylation of quinoxalin-2(1H)-ones has been described. This reaction utilizes 4-alkyl-1,4-dihydropyridines (R-DHPs) as alkyl radical precursors and acetoxybenziodoxole (BI-OAc) as an electron acceptor to und

Condensation of o-phenylenediamines (I) with 4-arylidene-2-substituted-oxazolin-5-ones (II) (azlactones) in acetic acid results in the formation of 3-benzyl-2(1H)quinoxalinones (III) and substituted benzimidazoles (IV).Structures of these compounds have been established based on their spectral data, and direct comparison with authentic samples prepared by unambiguous routes.
