Conversion of dibromides carrying O-functional groups at adjacent positions to the corresponding propargylic ethers was successfully carried out under the DBU conditions through 2-bromo-1-alkenes as intermediates. The optically active γ-lactone-class natural products, such as (-)-muricatacin (4) and (R,R)-sapinofuranone B (5) were synthesized using the propargylic ether intermediate produced by the elimination reaction mentioned above.
