Five simple preparative methods of (±)-prostaglandin B1 (PGB1) methyl ester are described. All routes were started from a common intermediate, 7-(2-hydroxy-5-oxo-1-cyclopentenyl)heptanoic acid derived from cyclooctanone via two steps. The key reaction of these routes is a palladium-catalyzed vinylation. The methods provided other PGB1 congeners and are applicable to synthesize 11-functionalized PG systems.
