実験手順
At 50°, 250 mg. of (5Z,13E)-(8R,9S,11R,12R,15S)-1-(N-methylcarbamoyloxy)-11,15-bis(tetrahydropyran-2-yloxy)-9-tribenzylsilyloxy-5,13-prostadiene was stirred for 5 hours in 15 ml. of a mixture of glacial acetic acid/water/tetrahydrofuran (65/35/10). The mixture was evaporated under vacuum and the residue purified by chromatography on silica gel with ether/dioxane (7+3), thus obtaining 105 mg. of the title compound as a colorless oil.
