合成路线1
该中间体在本合成路线中的序号:(A)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.

合成路线2
该中间体在本合成路线中的序号:(XI)The reaction of sec-butyl crotonate (I) with butylmagnesium bromide (II) by means of Cu2Cl2 in refluxing ether gives sec-butyl 3-methylheptanoate (III), wich is condensed with dimethyl methylphosphonate (IV) by means of butyllithium in THF at -70 C to afford dimethyl 2-oxo-4-methylphosphonate (V). The Wittig condensation of (V) with 1alpha-acetoxy-2alpha-(6-methoxycarbonylhexyl)-3beta-formyl-4alpha(tetrahydropyranyloxy)cyclopentane (VI) by means of NaH inTHF yields methyl 9alpha-acetoxy-11alpha-(tetrahydropyranyloxy)-15-oxo-17,20-dimethylprost-trans-13-enoate (VII), which is reduced with NaBH4 in methanol to the 15-hydroxy compound (VIII). Selective hydrolysis of (VIII) with p-toluenesufonic acid in methanol gives the 11, 15-dihydroxy derivate (IX), which is then treated with dihydropyran and p-toluenesulfonic acid in methylene chloride to afford the bis-tetrahydropyranyloxy compound (X). The reactin of (X) with diphenydiselenide (XI) by means of butyllithium and diisopropylamine in THF at -70º affords the 2-phenylseleno compound (XII), which by treatment with H2O2 and NaHCO3 in ethyl acetate - THF is converted into methyl 9alpha-hidroxy-11alpha, 15lpha-bis(tetrahydropyranyloxy)-17S, 20-dimethylprosta-trans-2, trans-13-dienoate (XIII). The hydrolysis of (XIII) with KOH in ethanol gives the corresponding free acid (XIV), which is oxidized with CrO3 - H2SO4 - MnSO4 in water - ether to afford 9-oxo-11alpha, 15alpha-bis(tetrahydropyranyloxy)-17S, 20-dimethylprosta-trans-2, trans-13-dienoic acid (XV). Finally this compound is deprotected by treatment with hot aqueous acetic acid.
