An industrially available prostaglandin intermediate is converted into a new prostacyclin analogue with a cyclic ether instead of the unstable enol ether system.For the construction of the modified alkyl side chain two subsequent Horner olefinations are used.This reaction sequence includes a new methodology for the conversion of an aldehyde into a β,γ-unsaturated carboxylic acid by a three-carbon elongation.
