Introduction
Nitrogen containing heterocyclic compounds have received
much attention as it posses exciting biological activities such as
antimicrobial, anticonvulsant, cardiotonic, antifungal,
anticancer, antitumor agent, and anti‐inflammatory
activities so they are considered as important key elements.

Aim of work
Synthesis of some
heterocyclic nitrogen
derivatives with potential
biological activity.
Plan of work
1-Synthesis of some heterocyclic nitrogen compounds.
2-Studying the behavior of the synthesized compounds
towards organic reagents.
3-Elucidation the structures of the synthesized compounds via
chemical methods and spectroscopic methods {IR, NMR,
Mass, etc}.
4-Studying the biological activity of the synthesized
compounds towards some microorganisms such as bacteria
and fungi.
