4-Hydroxycoumarin ( and ) as well as 2-hydroxy-2,5-cyclohexadien-1-ones – were reacted with KO2/18-crown-6 in benzene. Initial deprotonation of the enol hydrogen was followed by nucleophilic attack by O2/t- (for and ) and/or autoxidation of the resulting anion (for and –). A convenient synthesis of 2,3-unsaturated-δ-valerolactones from the corresponding 2-cyclohexen-1-ones is also described.
