Abstract

A novel and efficient method for synthesizing various quinoxaline derivatives has been developed, utilizing rainwater as both a solvent and a catalyst. This approach represents a significant advancement in green chemistry, as it combines simplicity, rapidity, and convenience while avoiding the need for toxic or expensive reagents. The synthesis involves the condensation reaction of aromatic 1,2-diamines with aromatic 1,2-dicarbonyl compounds. Traditionally, these reactions require specialized solvents and catalysts, but in this method, rainwater serves a dual function, streamlining the process and minimizing environmental impact. The use of rainwater not only simplifies the reaction setup but also provides an eco-friendly alternative to conventional organic solvents. The condensation leads to the formation of quinoxaline derivatives, a class of compounds known for their diverse biological and pharmacological activities. The reaction proceeds smoothly at ambient temperature, significantly reducing the energy requirements typically associated with chemical syntheses. This innovative synthesis method demonstrates the potential of using natural resources like rainwater in chemical reactions, contributing to sustainable practices in the field of organic synthesis. The versatility of the approach allows for the preparation of a variety of quinoxalines, offering promising applications in medicinal chemistry and material science. The rapid and straightforward process opens new avenues for the synthesis of quinoxalines, showcasing the potential of rainwater as a green solvent and catalyst in synthetic chemistry.
