"Chemical Equation Presented" A highly torquoselective olefinatlon of alkynoates to provide functionalized tetrasubstltuted olefins, (E)-2-en-4-ynoic acids, Is described. Addition of Bronsted acids dramatically switched the mode of the Ag(l)-catalyzed cyclization of the resulting enyne carboxylic acids to give either tetronic acids or 2-pyrones.
