참여 물질

반응 단계

A solution of 3.2 g. (0.5 mole) of 1-hydroxy-2-(6-carboxy-2-cis-hexenyl)cyclopent-3-ene (Example 1132) in 60 ml. of reagent acetone is treated dropwise with a total of 6 ml. of 8 N chromic acid in sulfuric acid at 0° C. The oxidation is rather slow. The resulting mixture is dissolved in 200 ml. of water and the solution is extracted with six 50 ml portions of ether. The combined ethereal extracts are dried over sodium sulfate and the solvent is evaporated at reduced pressure to yield the product as a yellow oil.
