Participants

Reaction Steps

Isopropyl (Z)-7-[(1R,2S)-2-(3,3-ethylenedioxydecyl)-5-oxo-cyclopent-3-enyl]hept-5-enoate (3) (0.81 g) and benzophenone were dissolved in methanol. Under argon atmosphere, the solution was irradiated with 300-W high-pressure mercury lamp for 4 hours and 40 minutes. After evaporation of the solvent, the crude product was chromatographed on silica gel (n-hexane/ethyl acetate=3/2) to give isopropyl-7-[(1R,2S,3 R)-2-(3,3-ethylenedioxydecyl)-3-hydroxymethyl-5-oxocyclopentyl]hept-5-enoate (4). Yield 0.41 g, 47%.
