organocatalytic enantioselective Strecker reaction was developed for the synthesis of α-amino nitriles that contain a thiazole moiety by using a cinchona-based squaramide catalyst. The corresponding products were obtained in good to excellent yields (up to 99 %) with excellent enantioselectivities (up to 98 % ee) by starting from aromatic-substituted imines. In addition, two trifunctional squaramides
