ether moiety instead of enol-ether skeleton in PGI2. The m-phenylene PGI2 and its derivative (Beraprost) were synthesized via dihydrocyclopenta[b]benzofuran derivatives as key intermediates by ortho-selective metal-halogen exchange reaction with Grignard reagents and subsequent copper-catalyzed cyclization. The ω-side chains were introduced by stereoselective epoxide formation or Prins reaction.
