Triethylamine → 2-Methylthio-4-hydroxy-4-octyl-2-cyclopentenone

Participants

Reaction Steps

A solution of 910 mg of sodium thiomethoxide dissolved in 100 ml of methanol was stirred under ice-cooling and stirring for 15 minutes. Triethylamine (6 ml) was added, and after the mixture was stirred for 10 minutes, a solution of the above crude oil of 2,3-epoxy-4-octyl-4-trimethylsilyloxycyclopentanone in 15 ml of methanol was added dropwise. After the mixture was stirred for 6 hours, the reaction mixture was poured onto saturated aqueous ammonium chloride, and the mixture was extracted with ethyl acetate. The organic layer was washed with saturated aqueous sodium chloride, dried over anhydrous sodium sulfate, filtered and concentrated to give a crude oil of 2-methylthio-4-hydroxy-4-octyl-2-cyclopentenone.
