The green chemistry approach is also termed a sustainable technology that involves the design, synthesis, processing, and use of chemical substances by reducing or eliminating chemical hazards [1]. This technique focuses on atom economy, the use of safer solvents or chemicals, the use of raw materials from renewable resources, the consumption of energy, and the decomposition of the chemical substances into non-toxic materials which are ecofriendly [2]. Several green techniques used in chemical synthesis include microwave irradiated organic synthesis (MIOS), ultrasound-induced synthesis (UIS), photo-catalysis, ball milling, and grinding techniques. To meet the requirement for environmentally friendly processes and products, green chemistry triggers chemical research for the processing of renewable feedstock to generate bioactive molecules [3]. The concept of the green chemistry approach was introduced to design the environmentally benign synthetic protocols for the synthesis of heterocyclic compounds that have a significant impact in several fields such as the use of green solvents, solvent-free organic synthesis, sustainable catalytic reagents, reduced energy consumption, improved atom economy, optimized reaction yields, use of alternate energy source, multicomponent reactions (MCRs), ionic liquids, high-efficiency, and time-saving reactions, etc (Fig. 2.1) [4].
