This study presents a novel and environmentally sustainable approach for the one-pot multicomponent green synthesis of pyrano[2,3-d]pyrimidine dione derivatives. The devised procedure involves a three-component condensation of aldehydes, malononitrile, and barbituric acid, employing a nanomaterial catalyst in the form of cobalt-doped iron tartrate. This catalyst, characterized by its nanoscale dimensions, demonstrates exceptional reusability and water solubility, contributing to its eco-friendly profile. The synthesis is conducted under reflux conditions, optimizing the reaction efficiency. Key attributes of the proposed protocol include the use of a non-toxic, cost-effective, and readily available catalyst. The high atom economy of the reaction signifies minimal waste generation, enhancing the sustainability of the synthetic process. Additionally, the reaction features a short duration, aligning with the principles of efficiency and resource conservation. Notably, the utilization of water as the solvent further enhances the green approach, minimizing the environmental impact. This innovative synthesis protocol not only addresses the growing demand for environmentally conscious methodologies but also showcases the potential for scalable and practical applications in organic synthesis. The integration of a reusable nanomaterial catalyst, coupled with the adoption of water as a solvent, positions this approach as a promising advancement in the pursuit of sustainable and green chemical practices. The study provides valuable insights into the development of efficient and environmentally benign synthetic routes for the production of pyrano[2,3-d]pyrimidine dione derivatives, paving the way for the exploration of greener alternatives in the realm of organic chemistry.
