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

An iron-catalyzed C(sp3)–H cyanoalkylation of glycinederivatives with cyclobutanone oxime esters was established for the incorporation of a cyano group into amino acids and peptides. In this reaction, Fe(NTf2)2 and pyridine-oxazoline ligands form highly active catalysts that could simultaneously and selectively activate both substrates. Preliminary mechanistic studies revealed the excellent chemo-selectivity

Amino acids and aromatic nitrogen heterocycles are widely used in pharmaceuticals. Herein, we present an effective visible-light-driven thiobenzoic acid (TBA)-catalyzed decyanative C(sp3)–H heteroarylation of glycine derivatives. This process occurs under mild and straightforward conditions, affording a range of valuable yet challenging-to-obtain α-heteroaryl amino acid derivatives. Moreover, this
