Peroxidase enzymesfrom various sources convert 2′,4,4′-trihydroxychalcone (1) into the novel quinol ether of 2-fromyl-6-hydroxycoumaranone (6), the structure of which was determined by X-ray diffraction; a biosynthetic pathway is suggested and capillarisin (11) may arise by a similar route.

Abstract The dioxetane derivative of 2′,4,4′-trihydroxychalcone, previously known as a product from peroxidase-catalysedoxidation, has now been detected in the dye-sensitized photooxygenation of the same chalcone and shown to be accountable for the host of other products formed.
