Reaction Conditions

Reaction Steps

A suspension of N-[(1S,2R)-1-cyano-4,4,4-trifluoro-2-methylbutyl]-4-methylbenzenesulfinamide (2.34 g, 7.69 mmol) in concentrated hydrochloric acid (75 mL) was heated to reflux for 18.5 h. After cooling to 25° C., the reaction mixture was washed with diethyl ether several times. The aqueous layer was concentrated to give a mixture of 5,5,5-trifluoro-L-alloisoleucine, NH4Cl, and toluenesulfonic acid (2.35 g). The crude amino acid was used in the next step without further purification. Mass spectrum (−ESI): 309 (M−H)−.
