Ynamides are special alkynes attached to the nitrogen atom bearing an electron-withdrawing group,which provides enhanced stability.The electronic properties and the reactivity of ynamides can be easily tuned by the selection of the electron-withdrawing group attached to the nitrogen,thus making them highly versatile synthons.Importantly,the nitrogen atom is able to impose an electronic bias,resulting in the highly regioselective attack of this electron-rich heteroatom-substituted alkyne by a large variety of nucleophiles.In our recent study on the use of heterosubstituted alkynes for heterocycle synthesis,we have realized an array of transition metal-catalyzed ynamide oxidation-,amination- and cycloisomerization-initiated tandem reactions,thus allowing the highly efficient and selective synthesis of versatile synthetically useful N -heterocycles.
