Participants

Reaction Steps

A solution of 500 mg (0.0014 mol) of methyl [[(6E,10E)-11-carbamoyl-2,6,10-trimethyl-3-oxo-6,10-undecadienyl]thio]acetate in 30 ml of methylene chloride is treated at 0° with 270 mg of m-chloroperbenzoic acid. The solution is stirred at 0° for 1 hour under argon. The reaction solution is washed with aqueous potassium carbonate solution. After drying and removing the solvent the residue is chromatographed on silica gel with ether-methanol 3:1. There is obtained methyl [[(6E,10E)-11-carbamoyl-2,6,10-trimethyl-3-oxo-6,10-undecadienyl]sulfinyl]acetate which exhibits the following absorption bands in the IR spectrum: 3329 cm-1, 3197 cm-1, 1734 cm-1, 1671 cm-1, 1639 cm-1, 1610 cm-1, 1439 cm-1, 1307 cm-1, 1218 cm-1, 1193 cm-1, 1148 cm-1, 1016 cm- 1.
