Photocatalytic difunctionalization of arylalkenes with quinoxalinones and dialkyl dithiophosphoric acids.

Here, a photocatalytic three-component reaction between arylalkenes, quinoxalinones and dialkyl dithiophosphoric acids was developed. This protocol allows the simultaneous incorporation of heterocyclic and dithiophosphoryl groups into a single molecule structure efficiently. These functionalities are important precursors in medicinal chemistry.
