    • PURPOSE: A manufacturing method of chiral A-aminonitrile is provided to efficiently and economically provide a large amount of chiral A-aminonitrile of high optical purity through stereoselective strecker reaction with imine or amidosulfone, which is a precursor thereof, and cyanide ion source which contains little toxicity and is easily handled. CONSTITUTION: A manufacturing method of chiral A-aminonitrile comprises a step of conducting a strecker reaction by using cyanide supply source under the presence of a catalyst indicated in chemical formula 1 or chemical formula 2. The cyanide supply source is selected form alkali metal cyanide, alkali metal cyanide and alkali metal salt of acid indicated in chemical formula 6, and alkali metal cyanide and sufinic acid indicated in chemical formula 7. In the chemical formulas, R is halogen, n is 1-5, M is an alkali metal, Ar1 is a C6-12 aryl group and Ar2 is a C6-12 aryl group.
