The Chemistry of Ynamides

Ynamides contain a triple bond directly connected to a nitrogen atom that bears an electron-withdrawing group. They represent an especially useful and emerging class of reagents, notably because of their strongly polarized triple bond, which enables the development of unique chemical transformations. While they were discovered by Viehe in 1972, their chemistry has remained little investigated and the renaissance of ynamide chemistry started at the dawn of the 20th century with the development of
