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
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.
