Zusammenfassung: | According to the preparation method, ammonium salt or amine salt, aromatic aldehyde and an active methylene compound are subjected to a Knoevenagel-Michael cascade reaction to synthesize the alpha-cyano-beta-amino acrylate compound, and the ammonium salt or amine salt is used as a catalyst and is also used as a reaction substrate. According to the present invention, the application range of the reaction substrate is well expanded, 21 beta-amino acrylate compounds are synthesized, and the synthesis of the alpha-cyano-beta-amino acrylate compounds still has the stable performance in the gram-level reaction. The method disclosed by the invention is simple to operate, high in product yield, good in purity, low in production cost and environment-friendly, and has a potential and wide application prospect in the field of organic catalytic synthesis.
