A truly green synthesis of α-aminonitriles via Strecker reaction

Debasish Bandyopadhyay, Juliana M Velazquez, Bimal K BanikOrganic and Medicinal Chemistry Letters 2011, 1:11 (4 October 2011)

Background
The classical Strecker reaction is one of the simplest and most economical methods for the synthesis of racemic α-aminonitriles (precursor of α-amino acids) and pharmacologically useful compounds.

Results
Indium powder in water is shown to act as a very efficient catalyst for one-pot, three-component synthesis of α-aminonitriles from diverse amines, aldehydes and TMSCN. This general rapid method is applicable to a wide range of amines and aldehydes and produces products in excellent yield.

Conclusions
The present one-pot, three-component environmentally benign procedure for the synthesis of α-aminonitriles will find application in the synthesis of complex biologically active molecules.
