ABSTRACT Carbazoles are an important class of aromatic compounds having numerous applications in pharmaceuticals, including anticancer, anti‐inflammatory, and antibacterial activity. Traditional synthesis methods, while successful, frequently use toxic chemicals, hazardous solvents, and energy‐intensive procedures, raising serious environmental problems. This study discusses current advances in green carbazole synthetic approaches, with a focus on environmentally friendly strategies such as microwave‐assisted reactions, photoredox catalysis, and the use of recyclable metal catalysts such as gold and palladium. Sustainable techniques, such as solvent‐free processes, aqueous systems, and renewable resources, are explored alongside mechanistic insights into improving atom economy and reducing waste. These changes, which incorporate green chemistry concepts, not only increase the sustainability of carbazole synthesis but also expand its therapeutic potential, paving the way for environmentally friendly advances in medicinal chemistry.
