efficient green C1 building blocks to synthesize bioactive quinazolin-4(3H)-ones by ligand-free photocatalytic C–C bond cleavage. Notably, protection of hydroxyl, carboxyl, amide, or secondary amino groups is not required. Mechanistic studies suggest that conjugated N,O-tridentate copper complexes act as novel photoinitiators under visible light.
呋喃-2-甲醛作为生物质衍生的化学品,被用作有效的绿色C1构建基块,可通过无配体的光催化C–C键裂解来合成生物活性喹唑啉4(3 H)-酮。特别地,不需要保护羟基,羧基,酰胺或仲氨基。机理研究表明,在可见光下,共轭的N,O-三齿铜络合物可作为新型光引发剂。
