2-Acyloxy-1,3-dienes are obtained by regioselective addition of carboxylicacids and N-protected amino acids to vinylacetylene derivatives, with (arene)(phosphine)ruthenium(II) complexes as catalysts.

promote the selective Markovnikov addition of both aromatic and aliphatic carboxylic acids to a large variety of terminal alkynes, enynes, and diynes as well as propargylicalcohols. In this way, a wide number of enol esters and β-oxoesters could be synthesized in moderate to good yields under mild conditions (60 °C) in an aqueous medium.
