An environmentally benign and highly efficient, biomimetic procedure for the nucleophilic addition of trimethylsilyl cyanide to imines (Strecker reaction) using β-cyclodextrin as a catalyst and water as solvent afforded α-aminonitriles in quantitative yields. The catalyst can be recycled a number of times without loss in activity.
