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 straightforward, mild, efficient, and general method has been developed for the synthesis of alpha-aminonitriles via Strecker reaction starting from aldehydes or ketones, amines, and trimethylsilyl cyanide in the presence of sulfated tungstate as a heterogeneous mild solid acid catalyst at room temperature and solvent free condition. The developed method has been successfully applied for the synthesis of a wide range of alpha-aminonitriles with variable functionality. (C) 2011 Elsevier Ltd. All rights reserved.
