Π-Extended Systems Based on Tetracyclic Benzo [4,5] Imidazo [2′,1′:6,1] Pyrido[2,3-D] Pyrimidines

Abstract

Recently, we have developed a fundamentally new method of constructing the derivatives of the heterocyclic system of benzo[4′,5] imidazo[2′,1′:6,1]pyrido[2,3-d]pyrimidine [1], which allowed the introduction of methyl and methylene into the molecule groups. It should be noted that some derivatives of the indicated heterocyclic system revealed antibacterial and ant monoamine oxidase properties [2,3].
