Reaction Steps
5-oxo-hexahydro-cyclopenta[c]pyrrole-2-carboxylic acid tert-butyl ester 1e (0.32 g, 1.42 mmol) was dissolved in 10 mL of dichloromethane, and trifluoroacetic acid (3.27 mL, 42.7 mmol) was then added to the solution in an ice-water bath. Upon completion of the addition, the reaction mixture was stirred at 0° C. for 30 minutes, then the solvent was evaporated to dryness to obtain the title compound hexahydro-cyclopenta[c]pyrrol-5-one triflutate 1f which was directly used in the further reaction.
