  acid with either ω-alkenols or α,ω-diols, followed by ozonolysis or Dess―Martin oxidation as appropriate, underwent intramolecular Julia―Kocienski olefination when treated with DBU. Macrocyclic α,β-unsaturated lactones of between 12- and 19-membered ring sizes were formed successfully using this tactic (24―44% yield, Z/E ≥ 3.5:1); however, diolides were selectively produced from precursors intended
