Reaction Conditions

Reaction Steps

To a solution of 1.9 g (0.0035 mole) of diethyl 1,4-dithiacyclohept-5-en-6-yl phosphate (Example 17) in a mixture of 10 ml of water and 20 ml of methanol was added portionwise 1.2 g (0.0039 mole) of potassium peroxymonosulfate. During the addition the solution was maintained at 0° C. The mixture was stirred for ten minutes after completion of addition. The reaction mixture was poured into 50 ml of water and was extracted twice with 50 ml of methylene chloride. The combined extracts were dried over anhydrous magnesium sulfate, and the solvent was evaporated under reduced pressure. The residue was combined with a similar residue from a previous experiment and was subjected to column chromatography on silica gel using acetone as eluant. Evaporation of the solvent yielded 0.90 g of diethyl 1-oxo-1,4-dithiacyclohept-5-en-6-yl phosphate.
