✦ Synopsis

The formation of 4-alkoxy-2(5H)-furan-A C H T U N G T R E N N U N G ones was achieved via tandem alkoxylation/lactonization of g-hydroxy-a,b-acetylenic esters catalyzed by 2 mol% of [2,6-bis(diisopropylphenyl)imidazol-2-ylidine]gold bis(trifluoromethanesulfonyl)imidate

g-Hydroxy-a,b-acetylenic esters containing three adjacent and structurally very different functional groups are very useful in the synthesis of highly functionalized organic molecules. [1, 2] This class of compound is normally prepared by treatment of an alkyl propiolate with nBuLi at À78 8C
