N-quinzolineshow various biological activities and have been synthesized from Coumarins. coumarins is popularly known for its antimicrobial, anti-inflammatory, pesticidal and antihypertensive activities etc. It is well known that the synthesis of heterocyclic compounds tend to contain multi-structure in a molecule. The ring formation involves the condensation reaction. The challenge is to develop the ring system by substitution of oxygen with nitrogen of creatine.
