• tetracyclic quinoline systems on privileged templates have significant biological properties, such as antitumoral [5][6], anti-inflammatory [7], antimalarial [8], antituberculosis [9], and antiplasmodial [10] activities. Accordingly, the synthesis of new families of such quinoline systems still attracts much
