Asymmetric Strecker Reactions Catalyzed by Thiourea Phosphonium and Ammonium Salts

Abstract The application of asymmetric phase‐transfer catalysis to the Strecker reaction of ketimines was realized utilizing bifunctional thiourea‐phosphonium salts. The asymmetric Strecker reaction of aldimines was also realized utilizing quaternary ammonium salts derived from amino acids. magnified image
