Photo-/electrocatalytic functionalization of quinoxalin-2(1H)-ones

The photo-/electrocatalytic functionalization of quinoxalin-2(1H)-ones has emerged as a promising and powerful approach for post-synthetic modification of quinoxalin-2(1H)-ones. This review provides an overview of recent developments in photo-/electrocatalytic functionalization of quinoxalin-2(1H)-ones including arylation, alkylation, fluoroalkylation, amination, phosphorylation, acylation, alkoxylation, thiolation, silylation, and annulation. The reaction scope and the related mechanism are also well discussed.
