The direct approach: The title couplingreactions of N‐aryl glycine esters with unmodified ketones occurred smoothly in the presence of tert‐butyl hydroperoxide (TBHP) or 2,3‐dichloro‐5,6‐dicyano‐1,4‐benzoquinone (DDQ) under mild conditions (see scheme). The oxidant used for CH activation determined the selectivity of the reactions for a particular type of ketone substrate.
visible-light-induced aerobic oxidative [2 + 3] cycloaddition reaction between glycine derivatives and styreneoxides has been disclosed that provides an efficient approach for the rapid synthesis of 1,3-oxazolidines under mild conditions. This photoinduced process is enabled by the formation of an electron donor-acceptor complex between glycine derivatives and benzyl iodides.

with unactivated alkenes has been accomplished. This visible light-driven protocol has been successfully applied to a broad scope of glycine esters and simple alkenes, giving rise to diverse substitutedquinoline derivatives in 18–84% yield under mild (at room temperature under air atmosphere) and operationally simple reaction conditions.

A direct aerobic oxidative dehydrogenative coupling reaction of glycine derivatives with electron‐rich arenes has been accomplished via the synergistic combination of organic‐dye mediated photoredox catalysis and Lewis acid catalysis. This process exhibits good tolerance of functional groups and provides rapid synthesis of arylglycine derivatives at room temperature under an air atmosphere. Moreover
