PROCEDURE

实验过程

To a solution of tert-Butyl N-(tert-butoxycarbonyl)-L-homoserinate (1.00 g, 3.63 mmol) in dichloromethane (50 mL) was added at r.t. pyridine (0.88 mL, 10.9 mmol) and Dess-Martin-periodinane (2.31 g, 5.45 mmol). After 90 min the reaction mixture was diluted with ethyl acetate (40 mL), washed with 10% sodium thiosulphate solution (30 mL), saturated sodium bicarbonate solution (40 mL), and brine (40 mL). The combined aqueous layers were extracted with ethyl acetate (50 mL) and the combined organic layers were dried over sodium sulphate and concentrated under reduced pressure.
