実験手順

To a solution of (2S,4S)-4-acetylthio- 2-(allyloxycarbonylmethyloxymethyl)-1-(4-nitrobenzyloxycarbonyl)pyrrolidine (4.25 g) in allyl alcohol (40 ml) was added sodium hydride (62.8% in oil suspension) (0.5 g) at -5°~0° C. in a nitrogen stream. After stirring for 1 hour, acetic acid (1 ml) was added to the mixture. The mixture was concentrated under reduced pressure to give a syrup. The syrup was dissolved in ethyl acetate (50 ml), washed in turn with water (50 ml) and brine (50 ml), dried over magnesium sulfate, and concentrated under reduced pressure to give a syrup. The syrup was subjected to a column chromatography on silica gel (30 g) and eluted with chloroform to give (2S,4S)-2-(allyloxycarbonylmethyloxymethyl)-4-mercapto-1-(4-nitrobenzyloxycarbonyl)pyrrolidine (2.29 g).
