A straightforward and efficient approach for the synthesis of 3-cyano-coumarin derivatives

Heterocyclic compounds constitute a fundamental class in organic and medicinal chemistry, playing crucial roles across various biological fields. Their significance stems from their diverse biological activities, making them valuable in the treatment of numerous diseases.

Oxygen heterocycles constitute a significant category of organic molecules widely present in nature, underscoring their profound importance in scientific research due to their diverse applications across various fields. Coumarins encompass a diverse array of compounds known for their broad spectrum of biological activities, such as ; Antioxidant, anticonvulsant, antitumor, anti-inflammatory, and antimicrobial activities making them invaluable in medicine, pharmacology, cosmetics, and the food industry. The biological effects and potential applications of coumarins are intricately linked to their specific chemical structures. Consequently, researchers routinely engage in the daily synthesis of coumarin derivatives through several methods, including the Perkin, Pechmann, and Knoevenagel reactions, as well as the Wittig, Kostanecki-Robinson, and Reformatsky reactions. These diverse synthetic routes offer various approaches to obtaining coumarins, depending on the starting materials and desired reaction conditions. to explore their varied applications.

In this context, our emphasis is on the synthesis of 3-cyano-coumarin and its derivatives. This study introduces a novel and straightforward synthesis method that achieves these structures in a short reaction time. The method is validated through spectroscopic analyses, demonstrating its efficacy in providing access to these compounds under mild and environmentally friendly conditions, with excellent yields
