Participants

Reaction Steps

A solution of (±)-7-(1,2-epoxy-5-oxocyclopentyl)-heptanoic acid (3.0 g) in glacial acetic acid (75 ml) was heated at reflux for 8 hours. The excess acetic acid was then removed in vacuo to give an oil which crystallised on standing. Recrystallisation from a mixture of water and ethanol gave (±)-7-(4-acetoxy-5-oxocyclopent-1-enyl)heptanoic acid (1.4 g), m.p. 62°-65° C.
