A number of 3,4-disubstituted isocoumarins and polysubstituted α-pyrones have been prepared in good yields by treating halogen- or triflate-containing aromatic and α,β-unsaturated esters, resp., with internal alkynes in the presence of a palladium catalyst. Synthetically, the methodol. provides an especially simple and convenient, regioselective route to isocoumarins and α-pyrones containing aryl, silyl, ester, tert-alkyl, and other hindered groups. The reaction is believed to proceed through a seven-membered palladacyclic complex in which the regiochem. of the reaction is controlled by steric factors.
