the hemiaminal with a cyanide source, allows for the straightforwardsynthesis of α‐amino nitriles. The methodology presented here, displays high levels of chemoselectivity allowing for the reduction of amides in the presence of functional groups such as ketones, imines, aldehydes, and acids, which affords a simple route for the synthesis of α‐amino nitriles with a broad scope of functionalities in high
Easy and straightforward access to α-aminonitrile units by one-potsynthesis through a reductive Strecker cyanation from readily available formamides. The reaction is broad in scope and the conditions are mild, inexpensive, and easy to set-up, providing numerous α-aminonitriles in good yields (34 examples, 41–94 % yield).

the synthesis of α-aminonitriles from aldehydes, amines, and trimethylsilyl cyanide using a catalytic amount of magnesiumbromide ethyl etherate in the absence of solvent. Rapid formation of products is observed at room temperature in a one-pot procedure under very mild conditions giving excellent yields of the title compounds.Key words: catalyzed Strecker's reaction, α-aminonitriles, magnesium bromide
The Strecker reaction was performed via a one-pot three component condensation of hetero aromatic/aromatic aldehydes, secondary amines and trimetylsilyl cyanide in the presence of propylphosphonicanhydride (T3P®) to accomplish the corresponding α-aminonitriles. The main advantages of this method are very short reaction time and excellent yields.

A magneticallyseparable graphitic carbon nitride nanocomposite (Fe3O4/g‐C3N4) as a catalyst for the three‐component condensation reactions of carbonyl compounds, amines and trimethylsilylcyanide was thoroughly investigated. The reaction of these three components was found to be efficient, economical and green and took place in the presence of a catalytic amount of the magneticallyseparable catalyst
