The Wittig reaction of 1alpha-acetoxy-2alpha-(6-methoxycarbonyl-hex-2-cis-enyl)-3beta-formyl-4alpha-(2-tetrahydropyranyloxy)cyclopentane (I) and dimethyl 2-oxo-3-(3-trifluoromethylphenoxy)propylphosphonate (II) by means of NaH in hot THF gives 9alpha-acetoxy-11alpha-(2-tetrahydropyranyloxy)-15-oxo-16-(3-trifluoromethylphenoxy)-17,18,19,20-tetranorprosta-5-cis-13-trans-dienoate (III), which is reduced with NaBH4 in methanol yielding the protected trihydroxy compound (IV). The partial hydrolysis of (IV) with K2CO3 in methanol affords the dihydroxytetrahydropyranyloxy compound (V), which by reaction with diphenyldiselenide (A) by means of 17-butyllithium and diisopropylamine in THF is converted into the mixed selenide (VI). The treatment of (VI) with H2O2 in THF-ethyl acetate gives methyl 9alpha,15alpha-dihydroxy-11alpha-(2-tetra)-17,18,19,20-tetranorprosta-2-trans-5-cis-13-trans-trienoate (VII), which is finally treated with HCl in THF-water to eliminate the tetrahydropyranyl group.
