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

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.

An efficient approach was developed for the α-arylation of imino amides with arylboronicacids. Different substrates were examined for this arylation reaction. For the α-arylation of N-phenylimino amide, due to the electron-withdrawing properties of the phenyl group, the tautomerization between the amide and the iminol is more difficult. Thus, low reaction rate and low conversion were observed. This
