Abstract
A novel approach to 3(2H)-furanones combines a transition-metal-catalyzed activation of alkynes with a heterocyclization and subsequent 1,2-alkyl shift. Starting 2-hydroxy-2-alkynylcarbonyl compounds can be prepared by simple oxygenation of alkynyl carbonyl compounds using 2-iodoxybenzoic acid (IBX).
