Evaluation of Antioxidant Activity of 2H-Chromene Derivatives through Optimized Green Synthesis

The increasing concern for environmental sustainability and the need for efficient and green chemical synthesis have driven the development of alternative methods for producing new compounds. In this study, we have synthesized a series of novel 2H-chromene derivatives using a one-pot multicomponent reaction under ultrasound sonication. The use of ultrasound sonication is a green and efficient synthetic method that utilizes sound waves to initiate chemical reactions. We optimized various reaction parameters, such as solvent, temperature, catalyst amount, and reaction time, to identify the best reaction conditions for the synthesis of the derivatives. The synthesized compounds were characterized using analytical techniques such as IR, mass, 1H and 13C NMR spectra, which confirmed the molecular structures of the derivatives. Furthermore, the antioxidant activities of the synthesized derivatives were evaluated and compared to those of ascorbic acid. The IC50 values of the derivatives were promising, indicating their potential as antioxidants. Overall, this study demonstrates the effectiveness of ultrasound sonication as a green and sustainable approach to the synthesis of novel compounds with potential biological activities. The use of one-pot multicomponent reactions also adds to the efficiency and simplicity of the synthesis method. These findings may have important implications for the development of new and sustainable chemical synthesis methods in the future.
