Transition Metal-Free Direct C-3 Arylation of Quinoxalin-2(1H)-ones with Arylamines under Mild Conditions

摘要

A transition metal-free direct C-3 arylation of quinoxalin-2(1H)-ones with arylamines has been explored. This reaction proceeded smoothly through a radical process under mild conditions and produced the desired arylation products in good yields. The reactions proceeded efficiently with a broad range of substrates and functional group tolerance.
