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.
