Cyclic amines bearing α-substituents are valuable building blocks for drug discovery and natural product synthesis. Introduction of α-substituents via site-selective replacement of C–H bonds is highly attractive but typically limited to protected amine substrates. Now, an operationally simple hydride-transfer-based approach enables the introduction of α-substituents on unprotected amines.
