PHOTOOXYGENATION OF 2',4,4'-TRIHYDROXYCHALCONE: IDENTITY WITH PRODUCTS FROM ENZYMIC OXIDATION
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.

PRODUCTS FROM ENZYMIC OXIDATION OF 2',4,4'-TRIHYDROXYCHALCONE: STRUCTURAL RECONSIDERATIONS
The enzymic products from peroxidase-catalysed oxidation of 2',4,4'-trihydroxychalcone react with diphenylsulphide to form diastereoisomers of 4',6-dihydroxy-2-(α-hydroxybenzyl)-coumaranone, consistent with their previously assigned dioxetane structure.
