A concise, straightforward and efficient method has been developed for the synthesis of α-aminonitriles by an one-pot three-component condensation of aldehydes or ketones, amines and trimethylsilyl cyanide catalyzed by MgI2 etherate under solvent-free conditions. This protocol has some advantages such as mild reaction condition, simple work-up, short reaction time and high product yields.

A mild and efficient procedure for the synthesis of α-aminonitriles is achieved by treatment of aldimines with trimethylsilylcyanide catalysed by MgI2 etherate.
An iridium-catalyzed reductive nucleophilicaddition to secondary amides is reported. After the iridium-catalyzed reduction, the resulting imines can undergo the Strecker reaction, the Mannich reaction, allylation, and [3 + 2]-cycloaddition. The method shows high chemoselectivity in the presence of other functional groups such as methyl ester.

Strecker reaction for the synthesis of α‐aminonitriles was developed. The milling of aldehydes, amines, and potassiumcyanide in the presence of SiO2 gave the corresponding α‐aminonitriles in good to high yields. The high efficiency of the mechanochemical Strecker‐type multicomponent reaction allowed the one‐pot synthesis of tetrahydroisoquinolines after a subsequent internal N‐alkylation reaction.

technology, we present herein the evaluation of an integrated borosilicate glass micro reactor in which 51 α-aminonitriles were synthesized via a series of continuous solution-phase and heterogeneouslycatalyzedreaction steps, affording analytically pure products in yields > 99.6 %. As an extension to this, the ability to selectivity synthesize aldehydic Strecker products in the presence of ketonic
