Transition‐Metal‐Free Multicomponent Reaction of Quinoxalinones with Alkenes and Zhdankin Reagent through Photoredox Catalysis.

A photo‐induced three‐component coupling reaction of quinoxalinones with unactivated alkenes and azidobenziodoxolone (ABX, Zhdankin reagent) was developed. The protocol provides an efficient approach for the synthesis of various bioactive organoazides with quinoxalinone scaffold in moderate to good yields under mild conditions. This reaction is environmentally friendly avoiding the use of expensive transition‐metal photocatalysts and stoichiometric oxidants. [ABSTRACT FROM AUTHOR]
