The review summarizes the data for the 2005–2020 period on the methods of synthesis of heterocycles containing the 3,3-dicyanoacrylamide fragment. A group of reactions based on the introduction of the ylidenemalononitrile fragment into an existing 2-oxo-containing azaheterocycle is considered. A number of processes have been described in which simultaneous formation of both the azaheterocycle and the 3,3-dicyanoacrylamide fragment takes place.
