ABSTRACT In the field of chemistry, 1891 was regarded as a turning point as Pietro Biginelli discovered a new class of heterocyclic compounds. In the hetero chemical industry, the Biginelli reaction has been utilized over the past 133 years to synthesize a variety of dihydropyrimidinones. Recent advancements have shown that nanomaterials can serve as highly efficient heterogeneous catalysts for the Biginelli reaction. Nanomaterials outperform conventional catalysts due to their large surface area, distinct electrical characteristics, and increased catalytic activity. Their use not only improves the Biginelli reaction's selectivity and efficiency but also adheres to green chemistry principles, making the procedure of synthesis more environmentally friendly and commercially feasible. The current study highlights the significant role of various nanoparticles and their composites in the synthesis of dihydropyrimidinones (DHPMs), underscoring their potential to advance both research and industrial processes. In the present work, emphasis has been placed on uncovering the mechanistic interactions between nanocatalyst surfaces and reaction intermediates, highlighting how these features govern reactivity, yield, and structural variations in DHPMs. These interpretations transform the review from a simple collection of data into an analytical framework for understanding and designing efficient Biginelli reaction systems.
