    • 16-Hexadecanolide 7 was opened with lithiated dimethyl methylphosphonate to generate a β-ketophosphonate and immediately subjected to Horner-Wadsworth-Emmons olefination with phenylacetaldehyde to yield β,γ-unsaturated ketone 8. The presence of the phenyl ring promoted isomerization of the double bond from the α,β- to the β,γ-position, which was essential for the required RCM. Standard mesylation conditions provided 5
