Sulfinimines (Thiooximine S-Oxides) Asymmetric Synthesis of (R)-(+)-(3-Phenylalanine from (S)-(+)-N-(Benzylidene)-p-Toluenesulfinamide. 

B. (S)-(+)-N-(Benzylidene)-p-toluenesulfmamide (3) 2 An oven-dried, 500-mL, one-necked, round-bottomed flask (Note 1), equipped with a magnetic stirring bar and rubber septum is charged with 10.35 g (66.8 mmol) of (S)-(-t-)-p-toluenesulfinamide (2). The reaction flask is placed under vacuum (1 mm) for 30 min to remove residual moisture. The vessel is then placed under an argon atmosphere and dichloromethane (135 mL) (Note 8) is added via cannula. The solution is stirred rapidly and 7.07 g...
