2,3-disubstituted acrylonitriles derivatives are among the most important molecules in medicinal chemistry due to their bioactivity and their role as starting compounds for many bioactive molecules. Many heterocyclic structures have been investigated as AChE enzyme inhibitors. Nowadays, E/Z acrylonitrile derivatives are being studied as new AChE inhibitors. This study aimed to synthesis new heteroaryl-acrylonitrile compounds using Knoevenagel condensation. In this context, acrylonitrile compounds with aryl and heteroaryl structures at positions 2 and 3 (respectively )were synthesized from the reactions of pyrazole aldehyde derivative (4) with various acetonitrile compounds. Synthesized novel heteroarylacrylonitrile derivatives (5a-d) containing pyrazole ring are potential AChE inhibitors. The structures of the synthesized compounds were elucidated by FTIR, 1H-NMR and 13C-NMR spectroscopic techniques.
