The reaction of 4-hydroxy-1-octyne (I), with chlorotrimethylsilane and imidazole in DMF gives 4-trimethylsilyloxy-1-octyne (II), which is converted into 1-iodo-4-trimethylsilyloxy-trans-1-octene (III) by reaction with bis(3-methyl-2-butyl)borane (A), trimethylamine oxide, NaOH and finally I2. The hydrolysis of (III) with acetic acid in THF affords 1-iodo-4-hydroxy-trans-1-octene (IV), which is oxidized with pyridinium chlorochromate in methylene chloride yielding 1-iodo-4-oxo-trans-1-octene (V). The Grignard reaction of (V) with vinylmagnesium bromide (B) in THF gives 4-hydroxy-4-vinyl-1-iodo-trans-1-octene (VI), which is protected with trimethylsilyl chloride as before yielding 4-trimethylsilyloxy-4-vinyl-1-iodo-trans-1-octene (VII). The reaction of (VII) with tert-butyllithium in ether and then with copper (1)-1-pentyne-tributylphosphine (C) in HMPT affords the copper salt (VIII), which is condensed with 2-(6-trimethylsilyloxycarbonyl-2-cis-hexenyl)-4-trimethylsilyloxycyclopent-2-en-1-one (IX) in ether - THF giving trimethylsilyl-9-oxo-11alpha,16-bistrimethylsilyloxy-16-vinyl-5-cis-13-trans-prostadienoate (X). The hydrolysis of (X) with acetic acid in THF-water yields 9-oxo-11alpha,16-dihydroxy-16-vinyl-5-cis-13-trans-prostadienoic acid (XI), which is finally methylated with diazomethane in ether.
