A simple and efficient one-pot, three-component method has been developed for the synthesis of α-aminonitriles. This Streckerreaction is applicable for aldehydes and ketones with aliphatic or aromatic amines and trimethylsilyl cyanide in the presence of a palladium Lewis acid catalyst in dichloromethane solvent at room temperature.
A distinct approach for the synthesis of α-aminonitriles has been discovered by three-component reaction of nitroarenes, aldehydes, and TMSCN using indium in dilute aqueous HCl at room temperature. The products were formed in high yields (86–96%) within a short period of time (5–20 min). This one-pot conversion consists of the following steps: (i) reduction of nitro compounds to amines, (ii) formation
