6-Azauracil, as a key analog of uracil, serves as a core structural motif in a variety of biologically active molecules. Therefore, the development of novel methods for its structural modification is of significant importance. In recent years, with the maturation of green and mild radical-based strategies, particularly photocatalysis and electrocatalysis, the radical functionalization of 6-azauracils has achieved notable progress. This review focuses on research advances since 2021 concerning the radical-mediated alkylation, arylation, acylation, silylation, and trifluoromethylation of 6-azauracils, with an emphasis on the design and mechanistic innovations of these new reaction methodologies.

Key words: 6-azauracils, radical reaction, photocatalysis, electrocatalysis
