A stereospecificsynthesis and the gastric antisecretory and diarrheal activity of a 3E,5Z diene analogue of misoprostol are described. The key intermediate in the synthesis was an alpha chain truncated acetylene that was obtained by a cuprate/enolate capture procedure on the corresponding cyclopentenone. Palladium-catalyzed coupling of the acetylene with methyl 4-iodo-3(E)-butenoate provided the conjugated

A 4-fluoro analogue of enisoprost was prepared and evaluated for gastric antisecretory and mucosal protective activity in animals. The synthesis centered upon cuprate chemistry but also involved a Wittig reaction to produce a cis fluoro olefinic moiety, a furan rearrangement/isomerization reaction to provide the necessary hydroxycyclopentenone, and a two-carbon-homologation procedure. The fluoro analogue was much less potent as a gastric antisecretory and mucosal protective agent than enisoprost.
