An efficientpalladium-catalyzed alkoxycarbonylation of terminalalkynes was developed using di-tert-butyl dicarbonate as the ester source. This protocol proceeded under mild conditions and exhibited a board substrate scope. The successful application of gram-scale synthesis and product derivatization further confirmed the synthetic utility of this method. Thus it provides a powerful route to the synthesis
