These compounds are considered “privileged scaffolds” due to their potential in developing novel therapeutic agents. Traditional methods for synthesizing TZD derivatives involve condensation reactions that typically require toxic catalysts and organic solvents, often resulting in low yields. These drawbacks have spurred the development of more sustainable and efficient synthesis methods. Recent advancements focus on green and efficient techniques, such as microwave heating, solid-phase synthesis, and the use of ionic liquids (ILs). ILs, particularly chiral ionic liquids (CILs), offer significant benefits, including non-volatility, recyclability, and high thermal stability, making them ideal for multicomponent reactions. Their use improves both sustainability and reaction efficiency.
