cyclopentanone (A) have been achieved by a Claisen-Schmidt reaction. A new hydrazone
derivative 1-(2, 5-bis ((E)-4-isopropyl benzylidene) cyclopentylidene)-2-(2, 4-dinitrophenyl)
hydrazine (B) was synthesized by reacting under reflux chalcone (A) with 2, 4-
dinitrophenylhydrazine and evaluated for its biological activities. The structure of the title
compound (B) was studied using different spectroscopic techniques such as 1 H and 13 C …
