Room-Temperature Arylation of Arenes and Heteroarenes with Diaryliodonium Salts by Photoredox Catalysis
摘要:
Aryl radicals produced by irradiation of diaryliodonium salts with visible light under the catalysis of [Ru(bpy)(3)](2+) undergo coupling with a wide range of arenes and heteroarenes, affording various biaryls through direct C-H arylation at room temperature.

developed in the presence of an organophotosensitizer, 3,7-di([1,1'-biphenyl]-4-yl)-10-(4-(trifluoromethyl)phenyl)-10H-phenoxazine that has highly negative reduction potential at its photoexcited state. The developed reaction conditions are mild and allow the intermolecular C-C bond formation of the generated aryl radical with electron-rich (hetero)arenes and C-B bond formation with bis(pinacolato)diboron

photocatalyst and other additives, the radical arylation of diverse arenes and heteroarenes has been achieved with aryldiazonium salts under visible‐light irradiation from a blue light‐emitting diode (LED). Although the course of some reactions can be rationalized by the formation of strongly light‐absorbing charge‐transfer (CT) complexes between the diazonium ion and the aromatic substrate, several
An efficient directing group free C−Harylation of anisoles via Pd/S,O-ligand catalytic system is reported. This method can be applied to a wide variety of anisole derivatives and aryl iodides and is also applicable for late-stage arylation of bioactive molecules.
obesity. However, several known SET7 inhibitors exhibit weak activity or poor selectivity. Therefore, the development of novel SET7 inhibitors is highly desirable and of great clinical value. In this study, we identified 2-79 as a new hit compound by structure-based virtual screening and further AlphaLISA-based biochemical evaluation. Via chemical optimization, the synthesized compound DC21 was confirmed
