実験手順

144 milligrams of optically inactive 3-acetoxy-5-hydroxycyclopent-1-ene prepared as in Example 1 and 460 milligrams of 2,3-dichloro-5,6-dicyano-p-benzoquinone (DDQ) were dissolved in 5 milliliters of dioxane, after which the resulting solution was heated with stirring for 48 hours at 60° C. The precipitate separating out after the reaction was separated by filtration, and the filtrate was concentrated under reduced pressure to obtain a crude product.
