Popis: |
A highly efficient transition metal-free oxidative chemo- and regioselective C–C bond coupling of pyrazolones and quinoxalinones mediated by K2S2O8 is described. This reaction can be conveniently carried out under mild conditions and gives various hydroxy-pyrazolyl quinoxalinone products in moderate to excellent yields in a short reaction time. |
