The first three-component organocatalyzed Strecker reaction operating on water has been developed. The manifold utilizes ketones (aldehydes) as the starting carbonyl component, aniline as the primary amine, acetyl cyanide as the cyanide source and N,N-dimethylcyclohexylamine as the catalyst.

sulfonic acid (MCM-41–SO3H) was found to be a highly efficient and recoverable heterogeneous catalyst for the three-component Streckerreaction of aldehydes or ketones and diverse amines using trimethylsilyl cyanide (TMSCN) to afford the corresponding α-aminonitriles under mild conditions in high to quantitative yields. The simple experimental procedure along with easy recovery and reusability of the
