Acetamido ring-substituted ECAA was used in heterocyclic syntheses of dihydropyridines and in synthesis of polyimides from 4-aminophenylsuccinic acid and 3-(4-aminophenyl)glutaric acid . 4-Acetylamino ring-substituted isopropyl 2cyanophenylacrylate was reported as a nonlinear optical material . Alkyl 2cyanoacrylates are a family of vinyl monomers renowned for their high reactivity and instant adhesive properties . Thus, isopropyl cyanoacrylate was reported in preparations of semipermeable membrane microcapsules and as fissure sealant in dental application .
