반응 단계
Using as the materials and reagents (1E,3S,5R)-1-iodo-3-(tert-butyldimethylsiloxy)-5-methyl-1-nonene (476 mg, 1.2 mmol), tert-butyllithium (1.54 mol/l, 1.56 ml, 2.4 mmol), 174 mg of 1-hexynylcopper, hexamethylphosphorous triamide (436 μl), (4R)-tert-butyldimethylsiloxy-2-(5-methoxycarbonylpentylthio)-2-cyclopenten-1-one (373 mg, 1 mmol), and isobutyric anhydride (448 μl), the same procedure was performed as in Example 1 to obtain methyl(11R,12S,13E,15S,17R)-9-isobutyryloxy-11,15-bis(tert-butyldimethylsiloxy)-17,20-dimethyl-7-thiaprosta-8,13-dienoate (466 mg, 65%).
