Reaction Steps

3-Allylthio-4-hydroxy-6-methyl-2-pyrone (5.95 g., 0.0300 mol), 30% hydrogen peroxide (3.85 g., 0.0330 mol), and 40 ml. glacial acetic acid were combined and stirred over night at room temperature. The clear solution was poured into 250 ml. ice water. The aqueous mixture was extracted with clhoroform. The CHCl3 was dried (Na2SO4) and evaporated in vacuo. The recovered pink solid was recrystallized from cyclohexane-benzene to recover 5.0 g. (78 percent) of the desired compound. One additional recrystallization from cyclohexane-n-hexane gave the pure compound, m.p. 111°-112°C.
