Procedure

N-(Cbz-leucinyl)-amino-propene (2.95 g, 9.7 mmol) was dissolved in methylene chloride (100 ml), then mCPBA (5.0 g, 29.1 mmol) was added and the reaction was stirred overnight. The reaction was diluted with saturated aqueous sodium bicarbonate, extracted with EtOAc, dried with magnesium sulfate, filtered, concentrated, and chromatographed (silica gel, 50% EtOAc: hexanes).
