A CuH-catalyzed hydroamination of alkenes using an amine transfer reagent and a silane provides chiral amines with high efficiency and stereoselectivity. However, the current technology has been limited to dialkylamine transfer reagents (R2NOBz). A modified type of monoalkylamine transfer enabled the synthesis of chiral secondary amines, including those derived from amino acid esters, carbohydrates, and steroids.
