Globally, breast cancer is the leading cause of mortality. Within the field of antibreast cancer drug design by several compound docking studies, eight new N-containing nonsteroid tetracyclic derivatives have been synthesized via regioselective intramolecular C-H functionalization by visible light. The adopted methodology is highly efficient, green, and sustainable to unload a new pathway with excellent yield. It offers a rapid, low-cost, catalyst-free method for creating physiologically active molecules from easily accessible substrates. The synthesized substances were described using spectroscopic methods like HRMS,
