Catalytic C–H amination: the stereoselectivity issue

Catalytic C-H amination has recently emerged as a unique tool for the synthesis of amines. This tutorial review highlights the existing protocols catalyzed by metal complexes (rhodium, copper, ruthenium, manganese and palladium) allowing diastereo- and enantioselective C-H amination. Substrate-, catalyst- and reagent-controlled methodologies are detailed. They involve either catalytic nitrene C-H insertion or C-H activation.
