Enantioselective control of free radical reactions has eluded organic chemists for decades. Echoed with the renaissance of photo-induced processes, or so called photocatalysis or photoredox catalysis in organic synthesis, photo-induced organic radical chemistry has regained its prominence in developing catalytic asymmetric radical reaction. The generally mild conditions inherited with photochemistry, particularly visible light photo-processes, have allowed for controllable generation of free radicals as well as the subsequent bond formations. The past five years have witnessed dramatic advances in exploring photo-induced catalytic asymmetric free radical reactions, and enormous potentials along this line are envisaged. This perspective gives a brief summary on the important advances in this field. Accordingly, the major advances are classified based on different radical species including α-amino/oxyl radicals, radicals generated from enones and its analogues, benzyl radicals, α-carbonyl radicals, polyhalogenated alkyl radicals and nitrogen radicals. Brief discussion of mechanism is presented whenever relevant.

Key words: photoredox catalysis, free radical reaction, asymmetric catalysis, synergistic catalysis
