The dioxetane derivative of 2',4,4'-trihydroxychalcone, previously known as a product from peroxidase-catalysed oxidation, 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. - Key Word Index: Dioxetanes; chalcones; photooxygenation.

Amorpha fruticosa seedlings contain two enzymes capable of catalysing reactions of 2',4,4'-trihydroxychalcone.One is a chalcone-flavanone isomerase, which has been purified and occurs as two isozymes.More interestingly, the second is a peroxidase, which oxidises the chalcone (1; R1 = R2 = OH, R3 = H) to a novel labile quinol enol ether, chalaurenol (6), whose structure is established by chemical studies and X-ray diffraction of the 6-O-methyl ether (5).The possible origins and role of chalaurenol in plant metabolism are discussed.
Chalaurenol: a Novel Product from Enzymic Oxidation of 2',4,4'-Trihydroxychalcone

Peroxidase enzymes from various sources convert 2',4,4'-trihydroxychalcone (1) into the novel quinol ether of 2-formyl-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.
