Abstract

A facile, efficient, three-step protocol for the synthesis of the unknown quinolino[2,3-c]cinnoline 5 is introduced. In addition, a new approach for the preparation of the biologically active neocryptolepines 8 in good overall yields is described. ... Quinolines and their heterofused derivatives represent an interesting class of nitrogen-containing heterocycles that have gained attention due to their broad biological activities including antimalarial, antiparasitic, antifungal, antibacterial, ...
