Bronsted acid-catalyzed efficient Strecker reaction of ketones, amines and trimethylsilyl cyanide

A general method for the one-pot, three-component Strecker reaction of ketones was developed using Bronsted acids as organocatalysts. A series of alpha-aminonitriles were obtained in good to excellent yields (79-99%). A preliminary extension to a catalytic enantioselective three-component Strecker reaction of ketones (up to 40% ee) is also described.
