実験手順

(2S,3R)-3-Ethylsulfanyl-2-(4′-fluoro-biphenyl-4-sulfonylamino)-3-phenyl-propionic acid methyl ester. To a solution of (2S,3R)-2-amino-3-ethylsulfanyl-3-phenyl-propionic acid methyl ester 4a (49 mg, 0.20 mmol) in methylene chloride (2.0 mL) is added triethylamine (0.060 mL, 0.43 mmol) and 4′-fluoro-4-biphenylsulfonyl chloride (66 mg, 0.24 mmol). This mixture is stirred under argon overnight at room temperature. The reaction is diluted with methylene chloride and washed with 1.0 N aq. HCl. The aqueous layer is extracted with methylene chloride. The combined organic layers are dried over Na2SO4, filtered, and concentrated under reduced pressure. The crude product is purified by column chromatography (silica gel, 20% EtOAc/hexanes) to give the desired product.
