A simple synthesis of (E)-alk-1-enyl mesylates from (E)-alk-1-enylphosphonates is reported. Construction of γ-hydroxy-α,β-unsaturated compounds was achieved by a two-step process involving dihydroxylation of the enol mesylates followed by HWE reaction of the resulting α-hydroxy aldehydes with activated methylphosphonates. Enantioselective synthesis of the title compounds is also reported.

analogues, travoprost and bimatoprost, was developed employing Julia-Lythgoe olefination of the structurally advanced phenylsulfone with an enantiomerically pure aldehyde ω-chain synthon. The novel convergent strategy allows the synthesis of a whole series of prostaglandin analogues of high purity from a common and structurally advanced prostaglandin intermediate.
