l-Proline catalyzed one pot synthesis of α-aminonitriles

l-Proline (20 mol %) was found to be an efficient organocatalyst for one pot synthesis of a variety of α-aminonitriles from aldehydes (1), amines (2) and trimethylsilyl cyanide (TMSCN, 3) in acetonitrile at ambient temperature giving good to excellent yields (72-95%).
