摘要：

The catalytic activation of pro-2-ynylic ethers HC=CCR2OMe towards carboxylic acids is controlled to regioselectively afford the functional enol esters (RCO2C)-C-1(=CH2)CR2OMe or (RCO2CH)-C-1=CHCR2OMe corresponding to the addition of the carboxylate to either C(2) or C(1) of the terminal triple bond, depending on the nature of the ruthenium catalyst precursor RuCl2(PPh3)( p-cymene) or Ru(eta(3)-2-methylpropenyl)(2)(dppe), respectively.
