Acetic Acid → HCID 54734732, compound

Participants

Reaction Steps

4-Hydroxy-3-isopentylthio-6-methyl-2-pyrone (4.5 g., 0.020 mol), 30% hydrogen peroxide (2.44 g., 0.0220 mol), and 35 ml. glacial acetic acid were combined and stirred over night at room temperature. The clear solution was diluted with a mixture of toluene and ethanol and the acetic acid was removed by codistillation in vacuo. A yellow liquid was recovered which solidified upon cooling. The compound was recrystallized from n-hexane to recover 2.5 g. (51 percent) of shiny yellow platelets. One additional recrystallization from n-hexane gave the pure compound as tiny white crystalline needles: m.p. 80°-81°C.
