Abstract：Using 5-substituted 3,4-dihalo-2(5H)-furanones as the substrates, the Sonogashira coupling reaction in the presence of palladium catalyst gave 28 novel compounds. The structure was confirmed by IR, 1H NMR, 13C NMR, MS and elemental analysis. The influences of reaction temperature and time, catalyst kinds and dosage, base kinds and dosage, solvent, and different substrates were investigated. Under the optimized conditions, including 3 mol% Pd(PPh3)4 as the catalyst and 10 mol% CuI as the cocatalyst, 6.0 equiv. KF as the base, toluene as the solvent, the cross-coupling reactions with propargylic alcohol, as well as terminal alkyl and aryl alkynes at 30 ℃ for 72 h gave the 2(5H)-furanone derivatives containing enediyne structure in moderate to good yields without the addition of other ligands.
