The use of 1,8-diazabicyclo[5.4.0]undec-7-ene (DBU) as the electron donor allows efficient and operationally simple access to a series of C3-aroylated and acylated quinoxalin-2(1H)-ones with moderate to good yields.ChemistryBiochemistry, Genetics and Molecular BiologyArticleSCOPUS10.1039/d4ob00630e2-s2.0-85192480079
