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.

copper‐catalyzed phosphorylation of glycine derivatives under air and at room temperature. The present cross‐dehydrogenative coupling allows various methoxyphenyl‐protected glycine derivatives to be phosphorylated using diverse alkyl and aryl phosphites through an oxidative coupling between Csp3−H and P−H bonds catalyzed by copper iodide. This method provides a new synthetic tool to obtain biologically active
