실험 절차

A solution of 2-(3-acetoxyoctyl)-2,3-epoxycyclopentanone (26.8 g.)[prepared as described in (g) above] in glacial acetic acid (500 ml.) was heated at reflux for 12 hours. The excess acetic acid was then removed in vacuo and the residue distilled under reduced pressure to give 5-acetoxy-2-(3-acetoxyoctyl)cyclopent-2-enone (24.7 g.), b.p. 164°-175°C./0.2 mm.Hg.
