Article abstract of DOI:10.1016/S0040-4020(01)91384-5

A procedure is described for the synthesis of furans from 3-alkyn-1,2-diols or 2-methoxy-3-alkyn-1-ols by palladium catalyzed intramolecular addition of alcoholic moiety to acetylene linkage followed by elimination of water or methanol.The intermediary 3-furylpalladiums can be trapped with allyl halides affording 3-allylfurans in good yields.
