have been synthesized effectively viapalladium-catalyzedaminocarbonylation of enynes in the presence of various amines, diaminoalkanes, and aminoalcohols. The products have been utilized as substrates in alkoxycarbonylation reactions using methanol as the nucleophile and Pd(PPh3)2Cl2 as the catalyst to afford novel ω-amidoesters in high yields and selectivities. Interestingly, the product obtained
