The threo-2-(cyclopent-2-enyl)-1-(2-oxocyclopentyl)ethanolderivatives (2) and (3) have been converted into (±)-prostaglandin I2 methylester and its15-epimer. The route involved halogenoetherification, hydrodehalogenation, Baeyer–Villiger oxidation, and methanolysis, to give the 5-hydroxyprostaglandin I1 derivatives (17) and (18). These hydroxy esters were mesylated, the 11- and 15-hydroxy groups
