STEREOSELECTIVE SYNTHESIS OF THE FUSED γ-LACTONE/δ-LACTONE CORE OF OPHIODILACTONES
摘要:
A promising precursor of ophiodilactones A and B, tetrameric phenyl propanoids isolated form the ophiuroid Ophiocoma scolopendrina, has been synthesized stereoselectively employing a halolactonization and an intramolecular epoxide-opening with a carboxylic acid as key reactions.
