The reaction of allylindium reagents and N-(cyanoalkyl)amides afforded fully-substituted 4-alkenylimidazoles in moderate yields via the In-mediated Barbier-type allylation of nitrile and the following dehydrative cyclization cascade.
A simple and efficient method has been developed for the synthesis of α-amino nitriles from aldehydes, amines and trimethylsilyl cyanide (Me3SiCN) in the presence of a catalytic amount of cyanuricacid at room temperature.

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 silicasulfuricacid at room temperature. The silicasulfuricacid is reusable and could be applied in subsequent reactions with comparable activity.

A novel, simple and efficient one-pot synthesis of α-aminonitriles has been achieved by a three-component condensation of carbonyl compounds, amines and trimethylsilyl cyanide in the presence of (bromodimethyl)sulfoniumbromide as a catalyst at room temperature. The products were obtained in high yields and in short reaction times.
