m-Chloroperbenzoic acid → Methyl 6-oxabicyclo[3.1.0]hexane-1-carboxylate

Participants

Reaction Steps

Methyl cyclopent-1-ene-1-carboxylate (30.0 g, 237.8 mmol) was dissolved in 20 mL of dichloromethane and 3-chloroperbenzoic acid (64.4 g, 373.3 mmol) was added. The reaction was allowed to stir vigorously for 2 hours. The reaction mixture was diluted with EtOAc and washed with 0.5 N NaOH. The organic layer was dried over sodium sulfate, filtered and concentrated to give 48.0 grams of methyl 6-oxabicyclo[3.1.0]hexane-1-carboxylate.
