Abstract

Sudheendra, P. Srinivas Rao and R.H. Udupi*

Series of some new Pyrazoline derivatives (6a1-a28) have been synthesized in excellent yields by condensing the hydrazide (4) prepared from Schiff base (3) with different chalcones. The structures of newly synthesized compounds were established on the basis of elemental analysis and spectral data. Few compounds showed significant biological activities.
