DNA-encoded library (DEL) technology is a powerful tool in the discovery of bioactive probe molecules and drug leads. Mostly, the success in DEL technology stems from the molecular diversity of the chemical libraries. However, the construction of DELs has been restricted by the idiosyncratic needs and the required low concentration (~1 mM or less) of the library intermediate. Here, we report visible-light-promoted on-DNA radical coupling reactions via an electron donor-acceptor (EDA) complex and a reversible adsorption to solid support (RASS) strategy. This protocol provides a unique solution to the challenges of increasing the reactivity of highly diluted DNA substrates and reducing the residues of heavy metals from photocatalysts. A series of on-DNA indole sulfone and selenide derivatives were obtained with good to quantitative conversions. It is anticipated that these mild-condition on-DNA radical reactions will significantly improve the chemical diversity of DELs and find widespread utility to DEL construction.

A transition metal-free synthesis ofN-(arylthio/seleno)ethyl sulfoxidminesviablue light-promoted radical sulfoximido-chalcogenization of aliphatic and aromatic alkenes was developed. The sulfoximidation process demonstrated high chemoselectivity and allowed a broad substrate scope, completing the sulfoximido-chalcogenization of alkenes in good yields.

FeCl3-catalyzed three-component aryl-selenylation of alkenes with good to excellent yields has been disclosed. This method is characterized by synthesis of complicated products in a single-step reaction, simple operation and readily available commercially reagents. Finally, a reasonable mechanism of FeCl3-catalyzed aryl-selenylation is proposed.
