Versuchsvorschrift

Benzyl 3-(2-ethylthioethylidene)-7-oxo-4-oxa-1-azabicyclo[3,2,0]heptane-2-carboxylate (704 mg) was dissolved in methylene chloride (40 ml) and treated with m-chloroperbenzoic acid (370 mg). The solution was stirred at 0° C. for 1.0 hour and washed with a dilute bicarbonate solution (×2). The extract was dried over MgSO4 and evaporated. Chromatography over silica gel yielded the title product as a mixture of R and S sulphoxides (295 mg);
