N-Tosyl-α-aminonitriles have been synthesised by a Strecker reaction of various N-tosyl aldimines with trimethylsilyl cyanide in the presence of catalytic amount of Amberlyst-15 polymer at room temperature under heterogeneous conditions.
The present invention is directed to novel compounds. These compounds can be useful in inhibiting the activity of GGTase I. The compounds can also be used as anti-cancer therapeutics including as part of methods for treating cancer, in assays, and in kits.

Asymmetric addition of diethylzinc to aldehydes catalyzed by new zinc-amides prepared by a rhodium-catalyzed asymmetric addition
was found to be an effective catalyst for the asymmetricaddition of diethylzinc to aldehydes 3 through a screening method for asymmetric catalysts, in which two catalyticasymmetric reactions are connected. The chiral zinc catalyst can be readily prepared catalytically from achiral imine 1 by the chiral rhodium–diene complex mediatedasymmetricaddition of dimethylzinc.
The Strecker reaction of N-tosylaldimines with trimethylsilylcyanide in the presence of catalytic amount of iodine at room temperature produces the corresponding protected α-aminonitriles in high yields.
