Short syntheses of (±)-2a-c, ether analogues of acetomycin (1a) are described. The approach is based on a novel entry to furanones by rearrangement of tert-butyl 1-vinylcyclopropane-1-carboxylates. The cyclopropanes are stereoselectively formed by the rhodium(II) catalyzed decomposition of vinyldiazomethanes in the presence of vinyl ethers.
