Push–Pull Ynamines and Push–Pull Ynamides: Synthesis, Structure, Reactivity, and Application
European Journal of Organic Chemistry, EarlyView.Push–pull ynamines and push–pull ynamides, which carry an EWG and an amino or amido group as EDG, are highly interesting classes of EDG‐EWG alkynes that have been intensively studied due to their exceptional reactivity. In this review, the synthesis, structure, reactivity, and application of push–pull ynamines, push–pull ynecarbamates, push–pull ...
