Copper-catalyzed oxidative direct C3-cyanoarylation of quinoxalin-2(1 H )-ones via denitrogenative ring-opening of 3-aminoindazoles
A convenient and efficient copper-catalyzed oxidative arylation of quinoxalin-2(1 H )-ones with 3-aminoindazoles is developed for the synthesis of cyanoarylated quinoxalin-2(1 H )-ones. Notably, 3-aminoindazoles are employed as efficient arylating agents via the cleavage of two C–N bonds. This oxida...

Summary: | A convenient and efficient copper-catalyzed oxidative arylation of quinoxalin-2(1
H
)-ones with 3-aminoindazoles is developed for the synthesis of cyanoarylated quinoxalin-2(1
H
)-ones. Notably, 3-aminoindazoles are employed as efficient arylating agents
via
the cleavage of two C–N bonds. This oxidative arylation of quinoxalin-2(1
H
)-ones involves a radical process and undergoes a sequence of 3-aminoindazole oxidation, two C–N bond cleavage, and cyanoaryl radical addition. |
