Knoevenagel–Michael product derived from Meldrum's acid, phenyl Meldrum's acid and formaldehyde was prepared as a pure, stable and crystalline product. This compound readily dissociates under the reaction conditions to produce methylene Meldrum's acid. This Knoevenagel–Michael product was used to explore a new application of methylene Meldrum's acid: the reaction with enamines.
