3-Aminoacrylonitriles, enamines, were obtained from the reaction of 3-methoxyacrylonitrile with aliphatic amines in appropriate solvent, in sealed tube in the presence of aqueous sodium hydroxide, or under reflux, in satisfactory yields. The reactions of 3-aminoacrylonitriles with isocyanates or isothiocyanates gave 3-amino-2-cyxanoacrylamides or 3-amino-2-cyanoacrylthioamides, respectively.
