The system HRP-H2O2 transforms the phenolic phenylpropenoidic compounds methyl ferulate, 4, isoeugenol, 6, eugenol, 8, and 3-O-methyldopamine, 12, into oxidative dimerisation products or compounds therefrom.Resinification occurs when an ortho-diphenol structure, as in caffeic acid, 3, dopa, 10, and dopamine, 11, is present.This behaviour could derive from the formation of phenoxy radicals arising from an oxidation effected by the horseradish peroxidase compound I, 20.Rat-liver microsomes and prostaglandine endo-peroxidase synthetase give O-demethylation of ferulic acid, 2, via a similar co-enzymatic system.The dimer 5 is obtained from methyl ferulate, 4, when treated with the biomimetic catalyst manganese(III)tetraphenylporphyrinate acetate (MnTPPOAc), 30, with iodosylbenzene as the oxidant.The bis(salicylaldehyde)ethylenediiminocobalt(II)-catalysed oxidation of ferulic acid, 2, with dioxygen in methanol gives some demolition products such as vanillic aldehyde, 33, methyl vanillate, 34, a methyl ketone, 42, and a β-keto acid, 44, which retains the original carbon atom skeleton.
