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
