Participants

Reaction Steps

To a solution of (2S,4S)-1-allyloxycarbonyl-4-benzoyloxy-2-(2-methyl-3-oxo-1-butenyl)pyrrolidine (0.23 g) in methanol (5 ml) was added 28% solution of sodium methoxide in methanol (0.13 ml) at ° C. and the resulting mixture was stirred at the same temperature for 1 hour. To this solution was added acetic acid (0.04 ml), and the mixture was poured into a mixture of brine and ethyl acetate. The organic layer was separated, washed three times with brine, dried over magnesium sulfate and evaporated. The residue was chromatographed on silica gel (20 ml) eluting with a mixture of n-hexane and ethyl acetate (1:1 V/V) to give (2S,4S)-1-allyloxycarbonyl- 4-hydroxy-2-(2-methyl-3-oxo-1-butenyl)pyrrolidine (0.14 g).
