                                    The activation of allylic prop-2-yn-1-ols by the [Ru(mu-O2CH)(CO)(2)(PPh3)](2) catalyst in the presence of carboxylic acids leads to unsaturated beta-ketoesters in one step. The utilization of optically active prop-2-yn-1-ols provides a new stereoselective access to optically active beta-ketoesters with retention of configuration at the propargylic carbon.
