Significance
The first organocatalytic asymmetric Strecker reaction using KCN as a cyanide source is described. N-Arylsulfonyl imines 1 react with KCN in the presence of 1 mol% of chiral quaternary ammonium salt 2 under biphasic conditions to give protected α-amino nitriles 3. Linear and branched alkyl substrates provide the products in high yields and enantioselectivities.
