ABSTRACT

The present work describes the synthesis of new pyrrolidines and chalcone derivatives. Synthesis of chalcones (10-17) were acheved by condensation of diacetyl with substituted benzaldehyds in ethanolic sodium hydroxide (50%)(1:2). The later compounds reacted with Schiff bases (1-8) to yield 1,2-bis(2,4,5-tri (4-aryl)pyrrolidin-3-yl)ethane-1,2-dione (20-27). The characterization of some resulting products were confirmed by physical properties, and spectral data UV-Visible, FT-IR, 1H NMR, 13C NMR.

Keywords: New Chalcones, pyrrolidine.
