実験手順

To a solution of methyl (Z)-7-[(1R,2S,3R,5S)-2-(t-butyldimethylsilyloxymethyl)-5-hydroxy-3-(2-tetrahydropyranyloxy)cyclopentyl]-5-heptenate (25) (109.9 g, 233.5 mmol) in ethyl acetate (450 ml), 5%-palladium on carbon (10.98 g) was added and the mixture was hydrogenated at ambient pressure and at room temperature. The reaction mixture was filtered and the filtrate was concentrated under reduced pressure to give methyl 7-[(1R,2S,3R,5S)-2-(t-butyldimethylsilyloxymethyl)-5-hydroxy-3-(2-tetrahydropyranyloxy)cyclopentyl]heptanate (26) (110.1 g, 232.9 mmol, 99.7%) as colorless oil.
