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 new method for the synthesis of chiral alpha-amino acid derivatives by enantioselective C-H arylation of N-aryl glycineesters with aryl boric acids in the presence of a chiral Pd(II)-catalyst has been developed. This work successfully integrates the direct C-H oxidation with asymmetric arylation and exhibits excellent enantioselectivity.

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
