Benzopyrones, also known as coumarins, are found in very significant amounts in plants, however they have also been found in microbes and animal sources. This family of chemicals was divided into various categories as a result of the structural diversity that was discovered there, ranging from simple coumarins to numerous other types of policycliccoumarins, including furocoumarins and pyranocoumarins. Due to their wide range of biological activity, simple coumarins and their analogues are a vast family of chemicals that have garnered attention. They have demonstrated value as CNS-active chemicals, antitumor, anti-inflammatory, antioxidant, hepatoprotective, antiviral, and anti-HIV agents. Many plant habitats include coumarins, which may also serve as a chemical defence against predators.Warfarin, an anticoagulant that prevents deep vein thrombosis, blood clot formation, and pulmonary embolism, is used in prescriptions where it suppresses vitamin K production. There are a number of ways to make coumarins, with the Perkin reaction between salicylaldehyde and acetic anhydride being a well-known example. The investigation of various synthesis processes and the pharmacological effects of coumarins are included in the current review.
