The use of N-bromosuccinimide enables a metal-free one-pot strategy for the synthesis of pharmaceutically important α-amino ketones from readily available benzylic secondary alcohols and amines. This reaction proceeds via three consecutive steps involving oxidation of alcohols, α-bromination of ketones, and nucleophilic substitution of α-bromo ketones to give α-amino ketones.
