The synthesis and gastric antisecretory activities of the delta 4,5-cis, delta 4,5-trans, and 4,5-acetylenic analogues of 15-deoxy-16-hydroxy-16-methyl prostaglandin E1 methyl ester are described. The key step in the preparation of these compounds involved the stereospecific conjugateaddition of a cupratereagent to the appropriate cyclopentenones. Although the trans and acetylenic derivatives were
