nucleophilic addition of lithiated ynamides to aryl imines are described. This work also features an aza-variant of a Meyer–Schuster rearrangement of γ-amino-ynamides and their synthetic utility in intramolecular ketenimine [2+2] cycloadditions. Efforts in developing an expeditious and convenient method for synthesizing γ-amino-ynamides via nucleophilic addition of lithiated ynamides to aryl imines are described
