Application

Cyanoacetic acid can be used as a reagent:
  • Along with acetic anhydride for cyanoacetylation of various pyrroles, indoles, and aniline derivatives. It can also be used in other reactions such as cyclizations, syntheses of coumarins and other heterocycles.
  • To prepare of key intermediate via Knoevenagel condensation in the total synthesis of 5-acetamido-substituted melatonin derivatives as MT3 receptor ligands.
  • In the synthesis of aminopyrrolinone derivatives by reacting Ugi adducts of cyanoacetic acid and aromatic aldehydes.

The Gewald reaction of sulfur, cyanoacetic acid derivatives, and oxo-component (G-3CR) yielding highly substituted 2-aminothiophene derivatives has seen diverse applications in combinatorial and medicinal chemistry. Its products are of great use in pharmaceutical industry mainly as small molecular weight inhibitors.
