There are several reports on the synthesis of alkylamines, but most of the reported methods are not suitable for the synthesis of hindered amines. In this research, we found that a coppercatalyst is effective for the formation of congested C−N bonds at room temperature. Control experiments revealed that a copperamide is a key intermediate. Moreover, when a chiral amine was used, a quaternary carbon

Catalyst-free and mild synthetic methods for the construction of hindered α-amino acidderivatives are presented herein. A wide range of hindered amino acid amides can be readily obtained from the reaction of α-halohydroxamates with a variety of amines, including anilines, primary amines, and secondary amines. Moreover, the aza/aza-[4+3] cycloaddition of in situ-generated aza-oxyallyl cations with
