A highly efficient, one-pot, three-component, solvent-free protocol for the synthesis of alpha-aminonitriles starting from their corresponding carbonyl compounds, amines, using Mitsunobu's reagent has been developed. Diversity of alpha-aminonitriles has been synthesized in good to excellent yields (80-99%) using various kinds of aldehydes/ketones and a variety of amines. (C) 2012 Elsevier Ltd.

A general method for the one-pot, three-component Strecker reaction of ketones was developed using Brønsted acids as organocatalysts. A series of α-aminonitriles were obtained in good to excellent yields (79–99%). A preliminary extension to a catalytic enantioselective three-component Strecker reaction of ketones (up to 40% ee) is also described.
