well‐developed and growing body of work in Cu catalysis, the potential of Cu to serve as a photocatalyst remains underexplored. Reported herein is the first example of visible‐light‐induced Cu‐catalyzed decarboxylative C(sp3)−H alkylation of glycine for preparing α‐alkylated unnatural α‐amino acids. It merits mentioning that the mild conditions and the good functional‐group tolerance allow the modification

A catalytic α-sp3 C–H oxidation of peptides and glycine amides was achieved under radicalcation salt catalysis in the presence of O2, producing a series of substituted quinolines. The scope of this reaction shows good functional group tolerance and high efficiency of the oxidative functionalization.

An auto-oxidation promoted sp3 C–H arylation reaction between N-aryl glycine derivatives and electron-rich arenes, leading to the formation of N-aryl α-aryl α-amino acid derivatives, is described. This atom-economical and environmentally benign reaction proceeds smoothly under mild reaction conditions and requires only Brønstedacid and oxygen (balloon). A plausible radical involved mechanism is proposed
A novel and efficient stable radical cation triarylaminiumsalt‐catalyzed aerobic double Friedel–Crafts alkylation reaction of glycine derivatives with indoles has been developed. The reaction was performed in the absence of any other additives under mild conditions and only requires an air atmosphere (or oxygen, 1 atm) as co‐oxidant.

Copper triflate catalyzedoxidative C–H functionalization of glycine derivatives with allyltributyltin has been established using oxygen or tert-butyl hydroperoxide as oxidant. Various glycine esters and glycine amides were suitable substrates for this oxidative allylation reaction and afforded the desired homoallylic amines in moderate to good yields.
