ABSTRACT

2-naphthyl chalcones where prepared by using Claisen-Schmidt condensation. In addition, Schiff bases were produced by condensation of benzyl amine with substituted benzaldehyde, adding the latter to the chalcones by 1,3-anionic cyclo addition to the double bond of chalcones afforded the corresponding heterocycles pyrrolidines (1-24). Spectral data and some physical properties were used to support the structure of the new products. The proposed reaction mechanism was investigated using (H.F) and steric energy (S.E) calculation the antibacterial activity for pyrrolidines had been tested through it’s effects on two kinds of bacteria.

Keywords: 1,3-anionic cycloaddition, 2-naphthyl chalcones, Schiff’s Bases, pyrrolidines, antibacterial activity.
