A simple and efficient method has been developed for the synthesis of α-aminonitriles by a one-pot three-component condensation of aldehydes, amines, and trimethylsilyl cyanide in the presence of a catalytic amount of sulfamic acid at room temperature.

Basic ammonium salts act as highly effective catalysts for the cyanosilylation of aldehydes and in Strecker-type aminonitrile synthesis using TMSCN as cyanide source at 25 degrees C under extremely mild conditions, affording very good to excellent yields of silylated cyanohydrins and alpha-aminonitriles.
