A range of alkynyldimethylaluminum reagents were added to N,N‐disubstituted formamides and the their acetals to provide the corresponding N,N‐disubstituted 3‐amino‐1,4‐diynes. Also, these reagents smoothly underwent the addition to N,O‐acetals to give the corresponding N,N‐disubstituted 3‐amino‐1‐ynes.
