Photoredox-Induced Functionalization of Alkenes for the Synthesis of Substituted Imidazolines and Oxazolidines

A one-pot, three-component cascade reaction combining photoredox catalyzed radical addition and formal [3 + 2] annulation was developed. With this approach, highly concise syntheses of imidazoline and oxazolidine derivatives have been achieved. The advantages of this transformation are good to excellent yields, mild reaction conditions, operational simplicity, and easy accessibility of raw materials

Regiospecific Three-Component Aminofluorination of Olefins via Photoredox Catalysis

Direct visible-light-mediated aminofluorination of styrenes has been developed with high regioselectivity. Shelf-stable <i>N</i>-Ts-protected 1-aminopyridine salt was used as the nitrogen-radical precursor, and the commercially available hydrogen fluoride-pyridine was used as the nucleophilic fluoride source. The synthesis of an analogue of <b>LY503430</b> was performed to demonstrate the synthetic value of this strategy
