[Uses]

Pyranocoumarin is useful in studying the antioxidant activity of different types of coumarin compounds via an in-silico model of DPPH.
[Definition]

ChEBI: Cyclocoumarol is a member of coumarins.
[Production Methods]

The production route for pyranocoumarin is not available in open literature. However, it can be inferred from its structure and on the chemistry of pyranocoumarins. Industrial manufacture would rely on constructing the coumarin core, typically via Pechmann type condensation, and then forming the fused pyran ring through an acid catalysed cyclisation step. After ring formation, the crude product would undergo purification such as solvent removal and crystallisation to yield technical grade material for formulation.
[Mechanism of action]

Inhibits blood-coagulation
[Pesticide Type]

Rodenticide
